It measures 0.125 inches thick, 3 inches wide, and 18 inches long, with a shipping weight of 1.91 pounds. A2 tool steel offers good wear resistance, moderate toughness, and minimal distortion during heat treatment, making it a reliable choice for fabricating punches, dies, gauges, and forming tools. This material is supplied in the annealed condition and is ready for machining before hardening. Machinists, tool and die makers, and industrial maintenance technicians are the primary users of this stock.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for both job shop and production toolroom environments. Its 3-inch width and 18-inch length provide enough material for a range of small to medium die components, jig parts, and wear plates. The tight dimensional tolerances make it appropriate for applications where accurate stock sizing reduces setup time at the machine. It is commonly used in light to medium-duty tooling where A2 air-hardening steel meets the hardness and toughness requirements without the complexity of oil- or water-hardening grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel construction for minimal distortion during hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock sizing\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining prior to heat treat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock for use in toolroom, die making, and precision machining applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis material is worked by qualified machinists and tool and die makers using conventional milling, grinding, and EDM equipment. Heat treatment should be performed by a qualified heat treat facility following AISI A2 recommended cycles. Always verify final hardness with a calibrated Rockwell tester after heat treatment. Handle ground or precision-machined surfaces carefully to avoid nicking edges that could affect die or gauge fit.\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: 3 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 plus 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: 1.91 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: 54594\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541394194738,"sku":"54594","price":120.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_f9cb2b3e-f10b-4112-b178-9b70dec88630.jpg?v=1785874696","url":"https:\/\/voomisupply.com\/products\/starrett-54594-a2-tool-steel-flat-stock-0-125x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
