Measuring 0.0625 inches thick, 3 inches wide, and 18 inches long, this flat stock is supplied in the annealed condition so it can be machined, profiled, and then air-hardened to final working hardness. The AISI A2 designation means the steel offers good dimensional stability during heat treatment and strong resistance to wear, making it a common choice for punches, dies, gauges, and cutting tools. The piece weighs approximately 0.95 pounds.\u003c\/p\u003e\u003cp\u003eAISI A2 flat stock in this size is suited to small-shop toolrooms and production machine shops fabricating custom tooling, jig components, or fixture plates. The 3-inch width and 18-inch length provide enough material for a range of die components or multiple smaller blanks cut from a single piece. The annealed supply condition allows straightforward milling, drilling, and surface grinding before heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel — good dimensional stability during heat treat and strong wear resistance\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal and grinding allowance\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition — ready for machining prior to hardening\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 for general toolroom and die-making 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 following established shop practices. Air-hardening operations require controlled atmosphere or vacuum furnace equipment to achieve proper hardness and minimize decarburization — follow the steel supplier heat treatment guidelines for A2. Always wear appropriate PPE when grinding or machining tool steel. Finished tooling installed in production equipment should be inspected dimensionally before placing into service.\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: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 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 plus 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\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 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: 57496\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543564452146,"sku":"57496","price":148.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_320d98a4-b13f-4504-bf98-09f21f82c0fd.jpg?v=1785920455","url":"https:\/\/voomisupply.com\/products\/starrett-57496-a2-tool-steel-flat-stock-1-16x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
