AISI A2 is a versatile cold-work tool steel known for its excellent dimensional stability during heat treatment and good wear resistance after hardening. This flat stock is ground to close tolerances, making it suitable for fabricating punches, dies, gauges, and other precision tooling components. Machinists, tool-and-die makers, and industrial maintenance technicians work with this material when a balance of toughness, wear resistance, and minimal distortion on air hardening is required.\u003c\/p\u003e\u003cp\u003eA2 tool steel flat stock in this size range is commonly used in job shops, toolrooms, and maintenance departments for producing or repairing die components, cutting tools, and fixture elements. The 18-inch length provides enough stock for multiple short tooling blanks or a single longer component. Its square cross-section profile simplifies layout and setup on surface grinders, mills, and lathes. This stock is supplied in the annealed condition, ready for machining before heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for minimal distortion during heat treat\u003c\/li\u003e\n\u003cli\u003eGround flat stock held to tight thickness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for consistent fit in tooling applications\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches supports precise layout and grinding\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches ensures full usable length\u003c\/li\u003e\n\u003cli\u003e18-inch bar length suitable for multiple tooling blanks from a single piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock for general toolroom, die-making, and precision machining applications where close dimensional tolerances are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis material is supplied annealed and should be machined to final form before heat treatment. Heat treating A2 tool steel requires controlled atmosphere or vacuum furnace equipment and should be performed by qualified heat treat personnel following recognized metallurgical procedures. Use appropriate personal protective equipment when cutting, grinding, or machining tool steel stock. Secure workpieces properly in vises or fixtures to prevent movement during machining 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 A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7\/8 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\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.94 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: 54781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539772932402,"sku":"54781","price":321.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_12ac719d-4cf0-4eea-a2dd-114ba2d8fa6b.jpg?v=1785844270","url":"https:\/\/voomisupply.com\/products\/starrett-54781-a2-tool-steel-flat-stock-7-8-x-7-8-x-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
