| Accounting Policies [Abstract] | |
| Basis of Consolidation | Basis of Consolidation The consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries. All significant intercompany accounts and transactions are eliminated. Certain reclassifications have been made to prior year amounts to conform with current year classifications.
|
| Revenue Recognition | Revenue Recognition Revenue, net of related discounts, rebates, returns and allowances is recognized when performance obligations are satisfied under the terms of a customer order or contract. This occurs when control of the goods and services has transferred to the customer, which is generally determined when title, ownership and risk of loss pass to the customer, all of which occurs upon shipment or delivery of the product, based on the applicable shipping terms, or when the service is performed. Shipping terms may vary for products shipped outside the United States depending on the mode of transportation, the country where the material is shipped and any agreements made with the customers. Freight and Handling Fees and Costs Freight and handling fees and costs billed separately to customers are included as part of net sales, and freight and handling costs expensed are included as part of cost of sales on the consolidated statements of operations.

| Cash Equivalents | Cash Equivalents Cash equivalents consist of highly liquid instruments with original maturities of three months or less. Cash equivalents are stated at cost, which approximates market.

| Accounts Receivable | Accounts Receivable |
| Inventories | Inventories |
| Property, Plant and Equipment and Depreciation | Property, Plant and Equipment and Depreciation |
| Computer Software and Amortization | Computer Software and Amortization |
| Goodwill | Goodwill Goodwill, net of accumulated impairment losses, representing the excess of the cost over the net tangible and identifiable intangible assets of acquired businesses, is stated at cost. Goodwill is not amortized but instead is tested at least annually for impairment as of June 1, or more frequently if events or circumstances indicate that the carrying amount of goodwill may be impaired. Goodwill may first be assessed based on qualitative factors (Step 0) to determine whether a quantitative goodwill impairment test is necessary. In fiscal year 2026, the Company performed the Step 0 qualitative assessment rather than immediately performing the Step 1 quantitative valuation as has been done historically. The qualitative assessment includes, but is not limited to, reviewing factors such as macroeconomic conditions, industry and market considerations, cost factors, reporting unit-specific financial performance and other events, such as strategy and primary customer base. When preparing the quantitative impairment test, potential impairment is identified by comparing the fair value of a reporting unit to its carrying value, including goodwill. Historically, the fair value has been estimated using a weighting of discounted cash flows and the use of market multiples valuation techniques for the SAO reporting unit and the Dynamet reporting unit in the PEP segment. The discounted cash flow technique requires the use of cash flow forecasts. The cash flow forecasts include significant judgments and assumptions related to revenue growth rates, which include perpetual growth rates, gross margin and weighted average cost of capital. The market multiples valuation technique includes significant judgment in the determination of the market multiples. If the carrying value of the reporting unit exceeds its fair value, any impairment loss is measured by the difference between the carrying value of the reporting unit and its fair value, not to exceed the carrying amount of goodwill.

| Intangible assets | Intangible assets |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets |
| Leases | Leases Determination of whether a contract is or contains a lease at contract inception is based on the presence of identified assets and the right to obtain substantially all of the economic benefit from or to direct the use of such assets. When it is determined a lease exists, a right-of-use ("ROU") asset and corresponding lease liability are recorded on the consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term. Lease liabilities represent the obligation to make lease payments arising from the lease. On the lease commencement date, the Company measures and records a ROU asset and lease liability equal to the present value of the remaining lease payments, discounted using the rate implicit in the lease (or if that rate cannot be readily determined, an incremental borrowing rate). Lease terms include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease contracts with a term of 12 months or less are not recorded in the consolidated balance sheets. Fixed lease expense is recognized for operating leases on a straight-line basis over the lease term. Lease agreements with lease and non-lease components, are accounted for as a single lease component for all underlying asset classes. Accordingly, all costs associated with a lease contract are accounted for as lease costs. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments. The variable lease payments are not presented as part of the ROU asset or lease liability.

| Environmental Expenditures | Environmental Expenditures |
| Derivative Financial Instruments | Derivative Financial Instruments All derivative financial instruments are recorded on the balance sheet at their fair value and changes in fair value are recorded each period in current earnings or other comprehensive income (loss). The Company enters into derivative financial instruments to hedge certain anticipated transactions, firm commitments or assets and liabilities denominated in foreign currencies.

| Foreign Currency Translation | Foreign Currency Translation |
| Income Taxes | Income Taxes Deferred income taxes are recognized by applying enacted statutory tax rates, applicable to future years, to temporary differences between the tax basis and financial statement carrying values of the Company's assets and liabilities. Valuation allowances are recorded to reduce deferred tax assets to amounts that are more likely than not to be realized. Significant judgments, estimates and assumptions are required in determining tax return reporting positions and in calculating provisions for income tax, which are based on interpretations of tax regulations and accounting pronouncements. Liabilities are established for uncertain tax positions when it is more likely than not that such positions, if challenged, would not be sustained upon review by taxing authorities. These liabilities are re-evaluated as tax regulations and facts and circumstances change, such as the closing of a tax audit or the expiration of the statute of limitations for a specific exposure.
|
| Earnings per Share | Earnings per Share The Company calculates basic and diluted earnings per share using the two class method. Under the two class method, earnings are allocated to common stock and participating securities (non-vested restricted shares and units that receive non-forfeitable dividends) according to their participation rights in dividends and undistributed earnings. The earnings available to each class of stock are divided by the weighted average number of outstanding shares for the period in each class. Diluted earnings per share assumes the issuance of common stock for all potentially dilutive share equivalents outstanding.
|
| Concentration of Credit Risk | Concentration of Credit Risk |
| Use of Estimates | Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

| Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Issued Accounting Pronouncements - Pending Adoption In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2024-03 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The guidance in this ASU improves the disclosures about a public business entity's expenses by requiring more detailed information about the types of expenses included within the income statement expense captions, such as: inventory purchases, employee compensation, depreciation and intangible asset amortization. This ASU does not change or remove current expense disclosure requirements, however, it does affect where this information appears in the notes to financial statements, as entities are required to include certain current disclosures in the same tabular format disclosure as the other disaggregation requirements in the amendments. For public business entities, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. ASU 2024-03 is a requirement for additional disclosure and is not expected to materially impact the consolidated financial statements. Additionally, in January 2025, the FASB issued ASU 2025-01 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which clarifies the effective date for non-calendar year-end entities. In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this update make targeted improvements to increase the operability of the recognition guidance considering different methods of software development. The ASU is effective for annual reporting periods beginning after December 15, 2027, and interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the potential impact of the adoption of ASU 2025-06 on its consolidated financial statements and related disclosures. In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815) Hedge Accounting Improvements. The update provides targeted improvements intended to enhance the application of hedge accounting, including expanded eligibility of forecasted transactions, additional flexibility in measuring hedge effectiveness and clarifications related to hedging non-financial items. The guidance is effective for annual reporting periods beginning after December 15, 2026, including interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the potential impact of the adoption of ASU 2025-09 on its consolidated financial statements and related disclosures. In December 2025, the FASB issued ASU 2025-12 Codification Improvements to address suggestions received from stakeholders on the Accounting Standards Codification and to make other incremental improvements to U.S. GAAP. The update represents changes to the Codification that (1) clarify, (2) correct errors or (3) make minor improvements. The amendments make the Codification easier to understand and apply. The guidance is effective for annual reporting periods beginning after December 15, 2026, including interim periods within those annual reporting periods. Early adoption is permitted. ASU 2025-12 is an update to correct, clarify and otherwise improve U.S. GAAP and is not expected to materially impact the consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements - Adopted In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The guidance in this ASU enhances the transparency and decision functionality of income tax disclosures to provide investors information to better assess how an entity's operations and related tax risks, tax planning and operational opportunities affect its tax rate and prospects for future cash flow. The amendments in this ASU require public entities to disclose the following specific categories in the rate reconciliation by both percentages and reporting currency amounts: the effect of state and local income tax, net of federal (national) income tax, foreign tax effects, effects of changes in tax laws or rates enacted in the current period, effects of cross-border tax laws, tax credits, changes in valuation allowances, non-taxable or non-deductible items and changes in unrecognized tax benefits. The amendments in ASU 2023-09 also require public entities to provide additional information for reconciling items that meet the qualitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pre-tax income (loss) by the applicable statutory income tax rate). The ASU requires reporting entities to annually disclose the year-to-date amount of income taxes paid (net of refunds received) disaggregated by federal, state and foreign localities. The Company adopted the provisions of ASU 2023-09 in the fourth quarter of fiscal year 2026. ASU 2023-09 is a requirement for additional disclosure, as such it did not impact the consolidated financial statements other than the disclosure requirements in Note 18. In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The guidance in ASU 2023-07 seeks to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this ASU require a public entity to disclose the following: significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss; an amount for other segment items by reportable segment and a description of its composition; and the title and position of the CODM and how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This ASU requires public entities to provide all annual disclosures about a reportable segment's profit or loss and assets currently required by Topic 280 in interim periods. ASU 2023-07 clarifies that if the CODM uses more than one measure of a segment's profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. The Company adopted the provisions of ASU 2023-07 in the fourth quarter of fiscal year 2025 and adopted the provisions for interim disclosures in the first quarter of fiscal year 2026. ASU 2023-07 is a requirement for additional disclosure, as such it did not impact the consolidated financial statements other than the disclosure requirements in Note 20.

| Fair Value Measurements | Fair Value Measurements |
| Fair Value of Financial Instruments | The Company's derivative financial instruments have historically consisted of commodity forward contracts and foreign currency forward contracts. These instruments are measured at fair value using the market method valuation technique. The inputs to this technique utilize information related to commodity prices and foreign exchange rates published by third party leading financial news and data providers. This is observable data; however, the valuation of these instruments is not based on actual transactions for the same instruments and, as such, they are classified as Level 2. The Company's use of derivatives and hedging policies are more fully discussed in Note 17. The Company has currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with U.S. GAAP.
