Manufactured to AISI A2 tool steel specification, this piece measures 0.1875 inches thick, 2.5 inches wide, and 18 inches long. Thickness tolerance is held to plus or minus 0.001 inches and squareness tolerance is held to plus or minus 0.001 inches, making it suitable for jigs, fixtures, punches, dies, and other tooling applications where dimensional accuracy before hardening is critical.\u003c\/p\u003e\u003cp\u003eA2 air-hardening tool steel is a widely used grade in general tooling and die work. It offers good dimensional stability during heat treatment compared to oil-hardening grades, which reduces distortion risk on flat components. This flat stock is suited for short-run and production tooling in machine shops, tool rooms, and maintenance facilities. It is typically cut, machined, and ground to final shape before being air-hardened and tempered to the required hardness for the intended application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for stable heat treatment with minimal distortion\u003c\/li\u003e\n\u003cli\u003eThickness: 0.1875 inches with plus or minus 0.001 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 2.5 inches with plus 0.000 to 0.005 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with plus 0.250 inch tolerance\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eReady to machine, grind, and heat treat to application requirements\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 use in toolmaking, die making, punch fabrication, and fixture construction wherever AISI A2 air-hardening tool steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of tool steel flat stock should be performed by qualified machinists using appropriate cutting fluids and tooling rated for hardened or semi-hardened steel. Heat treatment, including hardening and tempering of A2 tool steel, should be carried out by a qualified heat treater following the material manufacturer guidelines and applicable shop safety procedures. Always allow the workpiece to reach ambient temperature before taking final measurements. Personal protective equipment is required during all cutting, grinding, and heat treatment operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 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 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: 2.4 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: 54614\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542085632306,"sku":"54614","price":199.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_3820f5fd-b4f8-4463-bbb4-a77d7a20df8d.jpg?v=1785891635","url":"https:\/\/voomisupply.com\/products\/starrett-54614-a2-tool-steel-flat-stock-3-16x2-1-2x18in","provider":"Voomi Supply","version":"1.0","type":"link"}
