Measuring 0.125 inches thick, 4 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances, including plus or minus 0.001 inches on thickness and squareness. A2 tool steel offers excellent dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and forming tools. This piece is ready to machine and heat treat to working hardness. Machinists, tool and die makers, and industrial fabricators are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for job shop toolrooms, production die shops, and maintenance departments that require a reliable, machinable blank in a standard rectangular section. The 18-inch length provides enough stock for multiple smaller tool blanks or a single full-length component. The 4-inch width accommodates larger die sections or wide forming components without requiring additional material joining. AISI A2 air-hardening tool steel is a common specification in tooling environments where through-hardening with minimal distortion is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for low distortion during heat treatment\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n  \u003cli\u003eSquareness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n  \u003cli\u003eStandard rectangular section ready for machining, grinding, and heat treating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank for use in toolmaking, die making, and precision fabrication applications requiring air-hardening material in a 0.125 inch by 4 inch by 18 inch section.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and heat treating of A2 tool steel should be performed by qualified machinists or tool and die makers familiar with air-hardening steels. Always follow established shop safety practices when cutting, grinding, or heat treating tool steel. Allow the workpiece to cool uniformly after hardening to minimize stress and distortion. Consult the material specification sheet for recommended hardening temperatures and procedures before heat treatment.\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: 0.125 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: 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 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.58 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: 54596\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543500652850,"sku":"54596","price":218.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_e8b265b0-48a2-4bd8-9777-64334b477daa.jpg?v=1785919572","url":"https:\/\/voomisupply.com\/products\/starrett-54596-a2-tool-steel-flat-stock-0-125x4x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
