Measuring 0.125 inches thick, 1.75 inches wide, and 18 inches long, this flat stock is held to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus or minus 0.001 inches on squareness, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. AISI A2 tool steel offers good dimensional stability during air-hardening, making it a reliable choice for punches, dies, gauges, and similar precision tooling applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance departments that fabricate or replace tooling in-house. The 18-inch length provides enough material for multiple smaller blanks or a single longer workpiece. It arrives in the annealed condition, ready for machining prior to heat treatment. Typical users include tool and die makers, moldmakers, and precision machinists working in metalworking or manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise, repeatable stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches — allows clean squaring of ends\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining and subsequent hardening\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 fabricating punches, dies, blades, gauges, and general precision tooling components where air-hardening tool steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel flat stock should be performed by qualified toolmakers or machinists familiar with tool steel processing. All grinding, milling, and EDM operations should be completed prior to hardening. Heat treatment should follow the material supplier guidelines for AISI A2, including proper soaking temperature and air-quench procedure. Personal protective equipment appropriate for hot-work operations is required during heat treatment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 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: 1.75 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: 1.12 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: 57508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544317231410,"sku":"57508","price":116.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_0f15883f-e7c0-42f8-907f-0712c6ae8021.jpg?v=1785926168","url":"https:\/\/voomisupply.com\/products\/starrett-57508-a2-tool-steel-flat-stock-1-8x1-3-4x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
