Measuring 0.5 inches thick, 10 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances: +0.010 to 0.015 inches on thickness, width, and squareness, and +0.25 inches on length. A2 tool steel offers good toughness, wear resistance, and dimensional stability during heat treatment, making it a reliable choice for dies, punches, gauges, and forming tools that require air-hardening heat treat cycles.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die shops, and in-house maintenance departments fabricating or reconditioning tooling components. The 10-inch width and 18-inch length provide sufficient material for medium to large die sections, forming blocks, or blanks that will be rough-machined before hardening. The air-hardening A2 grade reduces distortion risk compared to oil-hardening grades, making it a common specification when close final tolerances must be held after heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel per AISI material specification\u003c\/li\u003e\n\u003cli\u003eThickness: 0.5 inches with +0.010 to 0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 10 inches with +0.010 to 0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with +0.25 inch tolerance\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eSuitable for dies, punches, gauges, and precision 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 blank suitable for use in tool and die fabrication, punch press tooling, and precision machining applications where AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with AISI air-hardening grades. Follow the material manufacturer's recommended preheat, austenitizing, and air-quench procedures to achieve target hardness and minimize distortion. Always use appropriate personal protective equipment when cutting, grinding, or heat treating tool steel stock. Consult applicable shop safety codes and material data sheets before beginning any heat treatment operation.\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 A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 10 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: +0.25 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: 25.5 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: 57613\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538776031538,"sku":"57613","price":1522.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_57cccb42-36f2-4c9b-bd40-e1fe70717ff0.jpg?v=1785826400","url":"https:\/\/voomisupply.com\/products\/starrett-57613-a2-tool-steel-flat-stock-0-5x10x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
