Manufactured from AISI A2 tool steel, this flat stock measures 0.25 inches thick, 1.75 inches wide, and 18 inches long, with a shipping weight of 2.23 pounds. A2 tool steel offers good dimensional stability during heat treatment and resists wear in demanding cutting and forming applications. Thickness, width, and squareness tolerances all fall within +0.010 to +0.015 inches, and the length tolerance is +0.25 inches. This stock is supplied in the annealed condition and is ready for machining before hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, and cutting tools in machine shops, tool rooms, and industrial maintenance environments. The A2 air-hardening grade is a common choice where minimal distortion after hardening is required. It is appropriate for both short-run and production tooling work and is used by tool-and-die makers, machinists, and maintenance technicians working with precision tooling components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel construction for good dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eThickness: 0.25 inches with +0.010 to +0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 1.75 inches with +0.010 to +0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with +0.25 inch tolerance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: +0.010 to +0.015 inches\u003c\/li\u003e\n\u003cli\u003eSupplied annealed and ready for machining 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 for use in tool-and-die fabrication, punch and die sets, gauges, and similar precision tooling applications requiring air-hardening tool steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of A2 tool steel flat stock should be performed in the annealed condition before hardening. Heat treating to final hardness requires a controlled atmosphere or vacuum furnace to achieve the air-hardening properties of A2 steel and should be performed by qualified personnel following established metallurgical procedures. Always use appropriate personal protective equipment when cutting, grinding, or machining tool steel. Secure the workpiece firmly before any machining operation.\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 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: +0.010 to +0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to +0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to +0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.23 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: 57583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540168638770,"sku":"57583","price":182.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_960b9754-ddae-4028-830d-aeabaa598f27.jpg?v=1785847798","url":"https:\/\/voomisupply.com\/products\/starrett-57583-a2-tool-steel-flat-stock-0-25x1-75x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
