This flat stock measures 0.125 inches thick, 2.5 inches wide, and 18 inches long, with a weight of 1.59 pounds per piece. Manufactured to AISI A2 tool steel specification, it offers good dimensional stability during heat treatment and is suited for applications requiring moderate toughness combined with wear resistance. Thickness tolerance is held to plus or minus 0.001 inches, supporting close-tolerance tooling work from the raw stock stage.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock is commonly used in tool and die shops, maintenance and repair operations, and precision fabrication environments. It is appropriate for both production toolmaking and prototype work where consistent cross-section dimensions reduce setup and grinding time. The 18-inch length allows multiple blanks to be cut from a single piece for smaller tooling components. This stock is typically purchased by toolmakers, machinists, and industrial maintenance professionals working in job shops, manufacturing plants, and fabrication facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eThickness: 0.125 inches with plus or minus 0.001 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 2.5 inches with plus 0.000 to minus 0.005 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with plus 0.250 inch length tolerance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance held to plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock format reduces initial stock prep time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for use in general toolmaking, die making, and precision machining applications where AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and tooling rated for hardened or semi-hardened steel. Heat treatment to full hardness should be performed by a qualified heat treater following AISI A2 recommended cycles. Always wear appropriate PPE including eye protection and cut-resistant gloves when handling and cutting flat stock. Consult applicable shop safety standards before beginning any machining or heat-treating operations.\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: 2.5 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 minus 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: 1.59 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: 54593\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540407746866,"sku":"54593","price":157.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_73466746-1edd-405a-95c4-2b5d83af1399.jpg?v=1785854461","url":"https:\/\/voomisupply.com\/products\/starrett-54593-a2-tool-steel-flat-stock-0-125x2-5x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
