It measures 0.625 inches thick, 3.5 inches wide, and 18 inches long, and weighs 11.15 pounds. A2 tool steel offers a balance of toughness and wear resistance, making it well suited for punches, dies, gauges, and cutting tools that require air hardening after machining. The tight tolerances held on this stock — plus or minus 0.001 inches on thickness and squareness — reduce the amount of finish grinding required before heat treat. Machinists and toolroom technicians are the primary users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is intended for toolroom and industrial fabrication environments where A2 air-hardening steel is specified. Typical applications include blanking dies, forming dies, punches, and precision gauging components. Because A2 hardens in still air rather than oil or water quench, it produces minimal distortion after heat treatment, which makes it a preferred choice when maintaining dimensional stability through the hardening process is critical. This bar is supplied in the 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 — minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition for machining prior to hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment\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\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat bar for toolroom and die-making applications requiring air-hardening material in annealed flat stock form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis material is worked by qualified machinists and toolroom technicians using conventional metal-cutting equipment. All machining should be completed in the annealed state before heat treatment is performed. Heat treating A2 tool steel to final hardness should be carried out by a qualified heat treat shop following the material manufacturer's recommended austenitizing temperature and soak time. Handle with care after hardening, as hardened tool steel is brittle and susceptible to edge chipping if dropped or struck.\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: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 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: 11.15 pounds\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: 54763\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540036747570,"sku":"54763","price":606.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_c2588d3b-b812-4f9a-b777-e5821619740d.jpg?v=1785845583","url":"https:\/\/voomisupply.com\/products\/starrett-54763-a2-tool-steel-flat-stock-0-625x3-5x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
