It measures 3\/32 inches thick by 1 inch wide by 36 inches long and ships at a weight of 1.1 pounds. A2 tool steel offers good dimensional stability during heat treatment and high wear resistance after hardening, making it a go-to choice for punches, dies, gauges, and fixture components. Machinists and tool-and-die makers rely on this grade for work that demands tight tolerances in the annealed state before hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabrication shops, tool rooms, and maintenance departments that work with precision tooling or custom fixtures. The 36-inch length provides enough material for most single-part applications without requiring additional cutting from a full bar. A2 air-hardening steel is commonly chosen when distortion control during heat treatment is critical, especially on thin cross-sections like this 3\/32-inch thickness. It is appropriate for both one-off tool repairs and short-run production of hardened components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for controlled distortion during hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance tooling work\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eAnnealed condition for machining prior to heat treat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock suitable for use in toolmaking, die making, punch fabrication, and precision fixture work where air-hardening steel is specified.\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 tool-and-die makers using appropriate cutting fluids and carbide or high-speed tooling. Secure the workpiece firmly before machining to avoid deflection on thin cross-sections. Heat treatment should be performed by a qualified heat treater following established procedures for A2 tool steel; improper hardening or tempering can result in cracking or inadequate hardness. Always wear appropriate personal protective equipment when cutting or grinding tool steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Air-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 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 0.25 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\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 57312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540456866098,"sku":"57312","price":168.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_7ce4ef68-59b9-458a-91c7-921ce4cf8838.jpg?v=1785855770","url":"https:\/\/voomisupply.com\/products\/starrett-57312-a2-tool-steel-flat-stock-3-32x1x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
