Measuring 5\/16 inches thick, 1-1\/4 inches wide, and 36 inches long, this flat stock is ground to tight dimensional tolerances, making it suitable for fabricating punches, dies, gauges, and other precision tooling components. It weighs 4.58 pounds. A2 tool steel offers good wear resistance and dimensional stability during heat treatment, and the air-hardening characteristic reduces the risk of warping or distortion compared to oil-hardening grades. Machinists and tool-and-die makers select this stock for work that demands consistent geometry and reliable hardening response.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in job shops, tool rooms, and industrial maintenance environments where custom tooling is fabricated in-house. Typical applications include cutting dies, form tools, fixture components, and wear plates. The 36-inch length provides sufficient stock for most bench-scale tooling projects and can be cut to length before or after hardening depending on application requirements. It is appropriate for both short-run production tooling and prototype work where dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel construction for dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal in grinding operations\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 tolerance of plus or minus 0.001 inches; edge squareness 0.003 per inch\u003c\/li\u003e\n\u003cli\u003e36-inch bar length suitable for a wide range of tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank for use in general toolmaking, die fabrication, and precision machining applications where air-hardening cold-work tool 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 tool-and-die maker using appropriate tooling and coolant. Heat treatment should follow the material specification for AISI A2 tool steel, including proper preheat, austenitizing, and air-quench procedures. Always allow the stock to cool fully before handling after hardening. Wear appropriate personal protective equipment when cutting or grinding.\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/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 (Edge)\u003c\/strong\u003e: 0.003 per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.58 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: 54633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541978349874,"sku":"54633","price":300.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_7f52bb49-0525-43a3-b2e1-0a1b974c041f.jpg?v=1785888719","url":"https:\/\/voomisupply.com\/products\/starrett-54633-a2-tool-steel-flat-stock-5-16x1-1-4x36in","provider":"Voomi Supply","version":"1.0","type":"link"}
