Measuring 0.15625 inches thick, 8 inches wide, and 36 inches long, it is manufactured to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. Squareness is held to 0.003 inches per inch on all edges. A2 tool steel offers good toughness and wear resistance with minimal distortion during air hardening, making it a reliable choice for dies, punches, gauges, and similar toolroom components. Machinists, toolmakers, and die makers work with this material in both job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for fabricating cutting tools, forming dies, blanking dies, and precision fixtures where dimensional stability through the hardening process is required. The air-hardening characteristic of A2 reduces warping and cracking compared to oil-hardening grades, making it appropriate for larger cross-section tooling. It ships in the annealed condition and is ready for machining prior to heat treatment. Shops working to close final tolerances will machine, finish, and then send out for heat treat or process in-house.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for minimal distortion during hardening\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock removal planning\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n  \u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n  \u003cli\u003eSupplied in annealed condition, ready for machining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general toolroom use as an OEM-style or replacement flat stock blank in applications requiring AISI A2 air-hardening tool steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining of A2 tool steel is performed in the annealed condition using standard carbide tooling. Heat treatment should be performed by a qualified heat treater following AISI A2 recommended cycles for austenitizing, air quenching, and tempering. Allow the bar to reach thermal equilibrium before quenching to reduce distortion. Follow applicable shop safety practices for handling hardened or sharp-edged stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2 Air-Hardening\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/32 inches (0.15625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.66 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539095388466,"sku":"57328","price":820.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_941291f2-a16e-4e01-ab9d-031d19947fdb.jpg?v=1785834670","url":"https:\/\/voomisupply.com\/products\/starrett-57328-a2-tool-steel-flat-stock-5-32x8x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
