Measuring 0.125 inches thick, 2 inches wide, and 18 inches long, it is manufactured to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus or minus 0.001 inches for squareness, and a width tolerance of plus 0.000 to 0.005 inches. The 18-inch length carries a plus 0.250-inch length tolerance. Machinists, toolmakers, and die shops rely on A2 grade stock for its excellent dimensional stability during air hardening, making it a preferred choice for punches, dies, gauges, and cutting tools.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for both prototype and production tooling environments. A2 tool steel responds well to conventional milling, grinding, and EDM operations in the annealed state before hardening. It is commonly used in job shops and in-house toolrooms where consistent stock dimensions are required for fixtures, stripper plates, and form tools. The 18-inch length provides enough material for multiple parts from a single piece, reducing setup changes on the mill or surface grinder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for excellent dimensional stability during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eReady for machining in the annealed state prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock suitable for general toolmaking, die making, and precision machining applications requiring air-hardening material in bar stock form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHandling and machining of tool steel flat stock is typically performed by machinists and toolmakers using conventional milling, grinding, or sawing equipment. Ensure proper workholding and coolant application during machining to maintain dimensional accuracy. Heat treatment should be performed by a qualified heat treater following A2 steel hardening and tempering procedures. Always allow stock to reach ambient temperature before final inspection 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: 0.125 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: 18 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 0.250 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\u003eWeight\u003c\/strong\u003e: 1.29 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: 54592\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543965532466,"sku":"54592","price":127.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_69e226c6-3b86-4831-9ead-9db7afdb0289.jpg?v=1785922537","url":"https:\/\/voomisupply.com\/products\/starrett-54592-a2-tool-steel-flat-stock-0-125x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
