A2 tool steel is an air-hardening, cold-work die steel known for its balance of wear resistance and toughness. It holds close dimensional tolerances, making it a reliable choice for fabricating dies, punches, gauges, and precision tooling components. The bar weighs approximately 40.64 pounds. Machinists, tool-and-die makers, and metalworking shops use this material when a through-hardening steel with good dimensional stability during heat treatment is required.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for applications in tool rooms, job shops, and manufacturing environments where cold-work tooling must maintain shape and hardness under repeated impact or forming loads. Typical uses include blanking dies, forming dies, shear blades, and gauging fixtures. The 18-inch length provides a practical starting cut for most tooling layouts without excessive waste. The 8-inch width accommodates wide die plates or multiple smaller blanks from a single piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel (AISI Type A2) for dimensional stability during heat treat\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 +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of +0.010 to 0.015 inches for predictable setup and fixturing\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock form; no profile grinding required before layout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank suitable for cold-work tooling applications in tool rooms and die shops requiring air-hardening steel in flat bar form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treatment of tool steel should be performed by a qualified machinist or tool-and-die maker using equipment appropriate for the material hardness. Follow the steel manufacturer's recommended austenitizing and air-quench cycle for A2 to achieve target hardness. Always allow the bar to reach room temperature before taking finish measurements, as thermal expansion will affect tolerance verification. Appropriate personal protective equipment must be worn during all cutting, grinding, and heat-treating operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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: +0.25 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: 40.64 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 57654\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541023523122,"sku":"57654","price":2086.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_a6ea596a-47fa-43f0-b18f-5fea83cfea5b.jpg?v=1785867445","url":"https:\/\/voomisupply.com\/products\/starrett-57654-a2-tool-steel-flat-stock-1x8x18-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
