Measuring 0.875 inches thick, 2 inches wide, and 18 inches long, this flat stock is ground to tight tolerances on all faces. The AISI A2 material designation means the steel achieves hardness through air quenching rather than oil or water quench, which reduces distortion during heat treatment. Licensed tool and die makers, machinists, and metalworking shops rely on A2 flat stock when dimensional stability after hardening is critical to the finished tool or component.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, jigs, fixtures, and cutting tools in job shops and production tool rooms. The 18-inch length provides enough material for most single-component tooling applications without the waste associated with longer bar stock. Its ground finish and close tolerances allow it to be used as-cut or with minimal additional stock removal before heat treatment and finish grinding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel — reduced distortion during heat treat compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent fit in precision setups\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 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 across all faces\u003c\/li\u003e\n\u003cli\u003eGround flat stock finish ready for layout, machining, or direct heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolmaking and die-making applications where air-quench steel is specified.\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. All grinding and heat treatment operations should follow established shop safety practices and applicable OSHA guidelines. Wear appropriate PPE including eye protection and heat-resistant gloves when handling stock during or after heat treat operations. Do not attempt air hardening without a controlled atmosphere or vacuum furnace to prevent decarburization of surface layers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.875 inches\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to plus 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: 8.96 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: 54782\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542248423730,"sku":"54782","price":522.28,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_0f94d33d-80a0-4e08-8b40-bbe84daec7da.jpg?v=1785896327","url":"https:\/\/voomisupply.com\/products\/starrett-54782-a2-tool-steel-flat-stock-7-8x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
