Measuring 0.75 inches thick, 6 inches wide, and 18 inches long, this flat stock is manufactured to close dimensional tolerances that support accurate layout and minimal stock removal before finishing. A2 tool steel offers good wear resistance and dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and other toolroom components. Licensed machinists, tool and die makers, and industrial maintenance technicians work with this material regularly.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, maintenance departments, and toolrooms that fabricate or repair cutting tools, forming dies, and precision fixtures. The A2 grade is commonly selected when moderate toughness and good wear resistance are required together, and when oil-quench distortion must be minimized. The 0.75 by 6 by 18 inch size provides enough material for medium-sized tooling blanks without excess waste.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel grade for reduced distortion during heat treatment compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness: 0.75 inches with a tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 6 inches with a tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with a tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance held to +0.010 to 0.015 inches for consistent layout reference\u003c\/li\u003e\n\u003cli\u003eSupplied as a single flat stock blank, ready for machining or grinding to final dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank suitable for toolroom fabrication of punches, dies, gauges, and precision fixtures requiring air-hardening tool steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate coolant and tooling rated for hardened or semi-hardened steel. Heat treatment should follow the A2 tool steel specification for austenitizing temperature and air-cool procedure — consult a qualified heat treater or the material specification for proper cycle parameters. Always wear appropriate PPE when cutting, grinding, or handling steel stock. Secure the workpiece properly before any machining operation.\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\u003eThickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 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: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22.95 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: 57631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538602754354,"sku":"57631","price":1148.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_b0fb6236-ffff-4601-874a-7792b6007230.jpg?v=1785825295","url":"https:\/\/voomisupply.com\/products\/starrett-57631-a2-tool-steel-flat-stock-0-75x6x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
