Measuring 0.5 inches thick, 8 inches wide, and 18 inches long, this flat stock is manufactured 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. A2 tool steel offers excellent wear resistance and dimensional stability during air-hardening heat treatment, making it a reliable choice for dies, punches, gauges, and forming tools.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool and die shops, and industrial fabrication environments. It is commonly used in the production of blanking dies, trim dies, and precision forming tools where consistent hardness and close tolerances are required. The 8-inch width and 18-inch length provide sufficient stock for medium-to-large tooling blanks. Machinists and tool and die makers typically rough-machine this material before heat treatment, then finish-grind to final dimensions after hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for excellent wear resistance and dimensional stability after heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches ensures consistent fit in die sets\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches supports accurate layout and machining\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches provides extra material for facing and squaring operations\u003c\/li\u003e\n\u003cli\u003eWeighs 20.16 pounds per piece — suitable for substantial tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for general tool and die fabrication, punch and die sets, gauges, and precision forming applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of A2 tool steel should be performed by qualified machinists or tool and die makers using appropriate cutting tools rated for tool steel. Always rough-machine before heat treatment and finish-grind after hardening to achieve final tolerances. Follow the material manufacturer's recommended heat treatment cycle for A2 steel, including proper preheat, hardening temperature, and air-quench procedure. Handle large flat stock with appropriate lifting equipment to prevent injury given the weight of this piece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Air-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 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: 20.16 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: 54757\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540964802866,"sku":"54757","price":778.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_9b1d1d6c-82ce-420f-8a6d-9d2cfdf9f48a.jpg?v=1785866586","url":"https:\/\/voomisupply.com\/products\/starrett-54757-a2-tool-steel-flat-stock-0-5x8x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
