Measuring 0.15625 inches thick, 4 inches wide, and 36 inches long, this flat stock ships in an annealed condition and hardens uniformly through an air-quench cycle, minimizing distortion compared to oil- or water-hardening grades. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy before hardening is critical. Weight is 7.33 pounds per piece.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock is a standard shop material for fabricating punches, dies, blades, gauges, and general tooling components. It is used in both prototype and production tool shops, tool-and-die operations, and precision machine shops. The 4-inch width and 36-inch length provide sufficient material for most standard tooling blanks without requiring initial saw reduction. This stock is appropriate for any application where a moderate-toughness, high-wear-resistance tool steel is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening grade minimizes distortion during heat treatment compared to oil- or water-hardening steels\u003c\/li\u003e\n\u003cli\u003eThickness tolerance: plus or minus 0.001 inches for precise pre-machined fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance: plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: plus or minus 0.001 inches; edge squareness held to 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e36-inch length accommodates most standard tooling blank requirements without preliminary cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI Type A2 air-hardening tool steel flat stock suitable for use in toolmaking, die making, and precision machining applications where A2 material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of A2 tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting fluids and tooling rated for tool steel. Heat treatment, including austenitizing and air quenching, should follow the material manufacturer's published cycle for AISI A2 and must be performed by personnel familiar with tool steel heat treatment procedures. Appropriate personal protective equipment is required during all machining and heat treatment operations. Always verify dimensional tolerances after any grinding or heat treatment step before final use in tooling assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/32 inches (0.15625 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.33 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: 54564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541514256690,"sku":"54564","price":349.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_af6d775c-93fc-4645-85f7-0620154bb6f4.jpg?v=1785878006","url":"https:\/\/voomisupply.com\/products\/starrett-54564-a2-tool-steel-flat-stock-5-32x4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
