A2 tool steel offers excellent dimensional stability during heat treatment and good toughness after hardening, making it a go-to material for dies, punches, gauges, and precision tooling components. This flat stock is ground to close tolerances — thickness held to plus or minus 0.001 inches and width held to plus 0.000 to 0.005 inches — so it arrives ready for layout, machining, or direct use in toolroom applications. Machinists, tool-and-die makers, and maintenance trades rely on this stock for fabricating or repairing precision components.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for toolroom, job shop, and industrial maintenance environments where close-tolerance, hardenable steel stock is required. Common applications include blanks for cutting tools, jig components, fixture rails, wear plates, and custom punches or dies. The 36-inch length provides practical stock for multiple short-run parts. Its air-hardening characteristic means less distortion risk compared to oil-hardening grades, which is important when dimensional accuracy after heat treat is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eGround flat stock with thickness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for predictable fit in close-tolerance layouts\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches — stock arrives at or slightly over 36 inches nominal\u003c\/li\u003e\n\u003cli\u003eReady for machining, grinding, or direct use as tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for toolroom fabrication, die and punch manufacture, and precision fixture components where a hardenable, ground-finish steel bar is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists or tool-and-die tradespeople using appropriate metalworking equipment. Follow established heat-treating procedures for AISI A2 steel per the material specification when hardening is required. Wear appropriate PPE including eye protection and cut-resistant gloves when handling and cutting steel bar stock. Inspect stock dimensions against your application tolerances before machining to finished size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1\/2 inch\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 on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 57330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541702574386,"sku":"57330","price":109.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_58aac6b4-67cd-440f-ba4b-ec9f6636d32f.jpg?v=1785882613","url":"https:\/\/voomisupply.com\/products\/starrett-57330-a2-tool-steel-flat-stock-3-16x1-2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
