Measuring 5\/16 inch thick by 4 inches wide by 18 inches long, this piece ships in an oversize, ground condition that allows machinists and tool-and-die professionals to cut, shape, and heat-treat to final dimensions. A2 tool steel offers good toughness and wear resistance after hardening, making it a reliable choice for punches, dies, gauges, and similar tooling components. The material conforms to AISI Type A2 specification and arrives ready for layout and machining.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, toolrooms, and maintenance departments that fabricate or repair tooling in-house. The 18-inch length provides enough material for multiple small components or one larger tool blank. The pre-cut flat format reduces saw time and material waste compared to ordering bar stock. Machinists, tool-and-die makers, and maintenance machinists are the primary users for this type of stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good wear resistance and dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eDimensions: 5\/16 inch thick x 4 inches wide x 18 inches long\u003c\/li\u003e\n\u003cli\u003eThickness tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance: +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: +0.010 to 0.015 inches\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 toolroom fabrication of punches, dies, gauges, and general tooling components requiring air-hardening steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified machinists or tool-and-die makers familiar with air-hardening steel procedures. Follow the material supplier guidelines and applicable shop safety standards when cutting, grinding, or heat treating. Appropriate personal protective equipment including eye protection and heat-resistant gloves is required during heat treat operations. Always allow the workpiece to reach ambient temperature before final inspection or finishing.\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 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\u003eShipping Weight\u003c\/strong\u003e: 6.38 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: 57183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539456983346,"sku":"57183","price":394.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_3ade3e71-96ee-4f31-987f-8a7f7afa6856.jpg?v=1785840656","url":"https:\/\/voomisupply.com\/products\/starrett-57183-a2-tool-steel-flat-stock-5-16x4x18-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
