Measuring 0.25 inches thick, 2 inches wide, and 36 inches long, this flat stock ships ready to cut, grind, and heat treat. A2 tool steel offers good dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and blades. Thickness and squareness tolerances are held to plus or minus 0.001 inches, giving machinists and toolmakers a consistent starting point without additional stock removal on face dimensions.\u003c\/p\u003e\u003cp\u003eThis flat stock suits job shops, tool and die makers, and maintenance machinists working in both light industrial and heavy manufacturing environments. It is appropriate for applications requiring moderate wear resistance and good toughness after heat treatment. The 36-inch length is a standard working bar that can be cut to finished blank sizes on a band saw or surface grinder. Width tolerance is held to plus 0.000 to 0.005 inches, and length tolerance is plus 0.25 inches from nominal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel — stable dimensions through heat treat cycle\u003c\/li\u003e\n\u003cli\u003eThickness: 0.25 inches with plus or minus 0.001 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 2 inches with plus 0.000 to 0.005 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 36 inches with plus 0.25 inch tolerance\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eAISI A2 material specification — suitable for punches, dies, gauges, and blades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank suitable for tool and die fabrication, fixture building, and precision component manufacturing where air-hardening steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and grinding of tool steel flat stock should be performed by a qualified machinist or toolmaker using appropriate coolant to prevent surface hardening or micro-cracking. Heat treatment to full hardness requires controlled atmosphere or vacuum furnace equipment and should follow AISI A2 recommended austenitizing and tempering cycles. Always allow stock to reach room temperature before final grinding to finished dimensions. Personal protective equipment including safety glasses and gloves is required when cutting or grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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: 5.86 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: 54580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544523702578,"sku":"54580","price":246.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_bef27e74-2665-4a4d-b237-d1423b85d67d.jpg?v=1785928744","url":"https:\/\/voomisupply.com\/products\/starrett-54580-a2-tool-steel-flat-stock-0-25x2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
