Measuring 0.375 inches thick, 1.25 inches wide, and 36 inches long, this flat stock is cut and ground to tight tolerances: thickness tolerance of plus or minus 0.001 inches, width tolerance of plus 0.000 to 0.005 inches, and length tolerance of plus 0.25 inches. A2 tool steel offers good wear resistance and dimensional stability through the hardening process, making it well suited for punches, dies, gauges, and forming tools that require predictable heat treatment response.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is used in tool and die shops, maintenance departments, and precision manufacturing environments. It is appropriate for machining into custom punches, blanking dies, stripper plates, and other tooling components where air-hardening steel is specified. The 36-inch bar length provides sufficient material for multiple parts to be cut from a single piece, reducing scrap. Squareness across all edges is held to 0.003 inches per inch, supporting accurate layout and machining from the blank state.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for predictable dimensional stability through heat treatment\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment in close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.25 inches provides consistent usable bar length\u003c\/li\u003e\n  \u003cli\u003e36-inch bar length suitable for sectioning into multiple tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose A2 air-hardening tool steel flat stock blank for use in tool and die fabrication, fixture building, and precision machining applications where AISI A2 material specification is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining should be performed by qualified machinists or toolmakers using appropriate metal-cutting equipment and coolant. Heat treatment to full hardness should follow AISI A2 guidelines and be performed by a qualified heat treater; air-hardening steels must be allowed to cool in still air and should not be quenched in water or oil. Inspect dimensions after any grinding or surface preparation before committing the blank to a finished tool profile. Wear appropriate personal protective equipment when sawing, grinding, or machining tool steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.25 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, all edges\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 54644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541828337970,"sku":"54644","price":247.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_81b6866f-bb3c-4504-83da-1ef8148f14f3.jpg?v=1785886074","url":"https:\/\/voomisupply.com\/products\/starrett-54644-a2-tool-steel-flat-stock-3-8-x-1-1-4-x-36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
