Measuring 1 inch thick by 3 inches wide by 18 inches long and weighing 15.12 pounds, this bar is produced to AISI A2 specification, which delivers excellent dimensional stability during heat treatment and strong wear resistance after hardening. Thickness tolerance is held to plus or minus 0.001 inch, squareness tolerance to plus or minus 0.001 inch, making it suitable for applications where pre-machined accuracy matters before hardening.\u003c\/p\u003e\u003cp\u003eA2 tool steel flat stock is a standard raw material in precision tool and die shops, mold shops, and maintenance machining environments. It is well suited for fabricating blanking dies, form dies, gauges, and wear plates where air-hardening capability reduces distortion compared to oil-hardening grades. This bar ships at a nominal 1 inch by 3 inch by 18 inch size, giving machinists usable stock for medium-run tool applications in both job shop and production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inch for consistent pre-machine stock accuracy\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inch\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock at 1 inch thick by 3 inches wide by 18 inches long\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat bar suitable for use in precision tool and die fabrication, gauging, and wear-plate applications where air-hardening tool steel stock is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists following recognized shop practices. Always wear appropriate PPE when cutting, grinding, or handling tool steel stock. Heat treatment, including hardening and tempering, should follow the material manufacturer's published cycle recommendations and be performed in properly controlled furnace equipment. Secure workpieces firmly before any machining operation to maintain the dimensional tolerances built into the bar.\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15.12 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: 54790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543876403506,"sku":"54790","price":789.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_3feccc4d-510e-435e-8ba7-24b6e497d7c1.jpg?v=1785922216","url":"https:\/\/voomisupply.com\/products\/starrett-54790-a2-tool-steel-flat-stock-1x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
