A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock is supplied in the annealed condition, ready for machining, grinding, and subsequent hardening by the end user. Machinists, toolmakers, and die makers use this material to fabricate punches, dies, gauges, and other precision tooling components. At 0.72 pounds per piece, it is well suited for small-batch tooling work and prototype applications.\u003c\/p\u003e\n\u003cp\u003eThis flat bar is appropriate for job shop, tool room, and industrial manufacturing environments where tight tolerance stock is required before final grinding and heat treatment. The controlled thickness, width, and squareness tolerances make it suitable for applications where near-net-shape blanks reduce secondary stock removal. Typical uses include cutting dies, forming tools, trim dies, and fixture components requiring moderate toughness and good through-hardness in sections up to approximately one inch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA2 air-hardening tool steel for minimal distortion during heat treatment\u003c\/li\u003e\n  \u003cli\u003eSupplied in annealed condition, ready for machining and grinding\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of +0.010 to +0.015 inches for consistent stock removal planning\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of +0.010 to +0.015 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of +0.250 inches\u003c\/li\u003e\n  \u003cli\u003eSquare tolerance of +0.010 to +0.015 inches for accurate layout and setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank compatible with conventional toolroom machining, surface grinding, and air-hardening heat treatment processes typical for AISI Type A2 cold-work tool steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA2 tool steel flat stock is machined and heat-treated by qualified toolmakers or machinists following standard tool steel processing procedures. All grinding and machining should be completed prior to hardening unless post-grind stock removal is planned. Follow established heat treatment guidelines for AISI A2 tool steel, including proper preheat, austenitizing temperature, and air quench procedures. Wear appropriate PPE when cutting, grinding, or handling tool steel stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +0.010 to +0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to +0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to +0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 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: 57597\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540572471602,"sku":"57597","price":162.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_e7a9ff9e-2183-47f9-942d-8ad8598c3927.jpg?v=1785858777","url":"https:\/\/voomisupply.com\/products\/starrett-57597-a2-tool-steel-flat-stock-3-8-x-3-8-x-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
