Manufactured from AISI A2 tool steel, this flat stock measures 3\/16 inches thick, 1-1\/2 inches wide, and 36 inches long, with a shipping weight of 3.3 pounds. The A2 designation indicates an air-hardening alloy known for its dimensional stability during heat treatment, reduced distortion, and good wear resistance. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications where close dimensional control is required before and after hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is used by tool and die makers, machinists, and maintenance professionals in job shops, production facilities, and toolrooms. It is commonly cut, ground, and machined into punches, dies, gauges, knives, and custom tooling components. The 36-inch length provides practical working stock for a range of part sizes. Width tolerance runs from plus 0.000 to plus 0.005 inches, and length tolerance is plus 0.25 inches, consistent with industry standards for precision ground flat stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock sizing\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches on 36-inch bar\u003c\/li\u003e\n\u003cli\u003eConsistent cross-section suitable for grinding to final dimension\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 air-hardening tool steel flat stock suitable for fabrication of punches, dies, blades, gauges, and custom tooling components where air-hardening alloy 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 tooling for hardened or pre-hardened steel. When heat treating, follow the material manufacturer recommendations for A2 steel austenitizing and air-quench procedures to achieve target hardness. Always use appropriate personal protective equipment when cutting or grinding tool steel stock. Verify final dimensions after any heat treatment cycle, as minor movement may occur even with air-hardening alloys.\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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/2 inches\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 plus 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, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.3 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: 54569\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541199585586,"sku":"54569","price":250.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_148ad0cb-b1d7-4c7a-9017-eed9469d1c8e.jpg?v=1785869960","url":"https:\/\/voomisupply.com\/products\/starrett-54569-a2-tool-steel-flat-stock-3-16x1-1-2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
