Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated statements include the accounts of Universal Stainless & Alloy Products, Inc. and its subsidiaries and are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reports and the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared under U.S. GAAP have been condensed or omitted pursuant to such regulations. Although the December 31, 2019 consolidated balance sheet data was derived from the audited financial statements, it does not include all disclosures required by U.S. GAAP. However, we believe that the disclosures are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with our most recently audited financial statements and the notes thereto included in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission. In the opinion of management, the accompanying financial statements include all adjustments necessary to present a fair presentation of the consolidated financial statements for the periods shown. Interim results are not necessarily indicative of the operating results for the full fiscal year or any future period. The preparation of these financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Actual results may differ from our estimates. The consolidated financial statements include our accounts and the accounts of our wholly–owned subsidiaries. We also consolidate, regardless of our ownership percentage, variable interest entities (each a “VIE”) for which we are deemed to have a controlling financial interest. All intercompany transactions and balances have been eliminated. When we obtain an economic interest in an entity, we evaluate the entity to determine if the entity is a VIE, and if we are deemed to be a primary beneficiary. As a part of our evaluation, we are required to qualitatively assess if we are the primary beneficiary of the VIE based on whether we hold the power to direct those matters that most significantly impacted the activities of the VIE and the obligation to absorb losses or the right to receive the benefits of the VIE that could potentially be significant. Refer to Note 7, New Markets Tax Credit Financing Transaction, for a description of the VIEs included in our consolidated financial statements.
New Accounting Pronouncement	Recently Adopted Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, “Disclosure Framework–Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, including the removal of certain disclosure requirements. The amendments in the ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the ASU. An entity is permitted to early adopt any removed or modified disclosures upon issuance of the ASU and delay adoption of the additional disclosures until the effective date. We adopted this guidance as of January 1, 2020 and the adoption did not have a material impact on our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740),” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments in this ASU also improve consistency and simplify other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU will be applied using different approaches depending on what the specific amendment relates to and, for public entities, are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020.
