Measuring 0.375 inches thick, 4 inches wide, and 36 inches long, this flat stock ships in a single piece at 17.59 pounds. A2 tool steel is an air-hardening, medium-alloy cold-work steel known for its dimensional stability during heat treatment and good wear resistance. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications where precise fitment before grinding is critical.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in the fabrication of dies, punches, gauges, forming tools, and precision fixtures in both job-shop and production environments. It is appropriate for applications where the steel will be finish-ground to final dimension after heat treat. The 36-inch length accommodates a wide range of blanking and machining layouts, and the 4-inch width suits medium to large tooling blanks. Licensed machinists, toolmakers, and die setters are the typical end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for stable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent pre-grind stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\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 air-hardening tool steel flat stock blank suitable for machining, grinding, and heat-treating operations typical of cold-work tooling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel should be performed by qualified toolmakers or machinists using appropriate coolant to prevent edge hardening during fabrication. Heat treatment of A2 steel requires controlled atmosphere or vacuum furnace equipment and should follow established AISI A2 austenitizing and air-quench procedures. Always allow stock to reach ambient temperature before measuring to final tolerance. Secure workpiece properly before any sawing or milling operation to prevent movement under cutting load.\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 Type A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 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 0.25 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\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17.59 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: 54650\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538922340658,"sku":"54650","price":584.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_47e186fb-59d8-4a26-8d76-c2cc59f2a67d.jpg?v=1785829745","url":"https:\/\/voomisupply.com\/products\/starrett-54650-a2-tool-steel-flat-stock-3-8x4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
