Cut to 3\/32 inch thick, 2 inches wide, and 18 inches long, this flat stock is produced to tight dimensional tolerances: plus or minus 0.001 inch on thickness, plus or minus 0.001 inch square tolerance, plus 0.000 to 0.005 inch on width, and plus 0.250 inch on length. AISI A2 tool steel is a versatile air-hardening grade known for good dimensional stability during heat treatment, making it a standard choice for blanks, punches, and forming dies. The piece weighs 0.97 pounds.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool-and-die operations, and maintenance departments that need a reliable A2 blank ready for layout, grinding, and hardening. The 18-inch length provides enough material for most standard tooling blanks and can be cut down to individual component lengths as needed. Machinists, tool-and-die makers, and industrial maintenance technicians are the typical end users. The stock ships in its annealed condition, ready for machining prior to heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good dimensional stability during hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inch for consistent stock removal calculations\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inch\u003c\/li\u003e\n\u003cli\u003eAnnealed condition — ready to machine before heat treat\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 toolmaking, die making, and precision machining applications requiring air-hardening tool steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified machinists or tool-and-die makers using appropriate cutting fluids and grinding equipment. Always follow the material manufacturer's recommended austenitizing and tempering temperatures for AISI A2 tool steel. Use proper personal protective equipment when cutting, grinding, or handling sharp-edged flat stock. Hardening operations should be conducted in a controlled atmosphere or with appropriate anti-scaling measures to maintain surface integrity.\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: 3\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.97 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: 57503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544541004082,"sku":"57503","price":148.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_3b64a85f-086e-46fa-b598-f50d17b00290.jpg?v=1785929283","url":"https:\/\/voomisupply.com\/products\/starrett-57503-a2-tool-steel-flat-stock-3-32x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
