Measuring 0.375 inches thick, 5 inches wide, and 36 inches long, it arrives in an annealed, ground condition ready for layout, machining, and heat treatment. A2 tool steel offers a balanced combination of wear resistance and toughness, and its air-hardening characteristic minimizes distortion during the hardening cycle. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications where dimensional consistency before heat treat is critical. Licensed machinists, toolmakers, and die makers are the primary users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, forming tools, and similar precision tooling components in job shops, tool rooms, and manufacturing facilities. The 36-inch length provides a workable bar that can be cut to multiple blanks on a horizontal bandsaw or cold saw. The 5-inch width accommodates larger die plates and mold components without requiring additional joining. AISI Type A2 designation confirms material specification for shops working to documented tooling standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel minimizes distortion during heat treatment compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for consistent pre-machined stock dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches provides a tight upper bound for fitted applications\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches allows full usable length on every bar\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges for reliable reference surfaces\u003c\/li\u003e\n\u003cli\u003eGround flat stock condition reduces setup time and material removal prior to final machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 tool steel flat stock suitable for toolroom and die-making applications requiring air-hardening material in ground flat bar form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting should be performed with appropriate metal-cutting equipment such as a cold saw or horizontal bandsaw with blade speeds suited for tool steel. Heat treatment including hardening and tempering should be performed by a qualified heat treater following established procedures for AISI A2 tool steel. Personal protective equipment including eye protection and appropriate gloves must be worn during all cutting, grinding, and handling operations. Inspect bar dimensions upon receipt before machining to confirm tolerances meet job requirements.\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: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5 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: 21.99 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: 54652\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541848293682,"sku":"54652","price":1047.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_47e73c41-661f-4555-a149-05a5ee4ec8e1.jpg?v=1785886729","url":"https:\/\/voomisupply.com\/products\/starrett-54652-a2-tool-steel-flat-stock-3-8x5x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
