It measures 5\/32 inch thick, 1 inch wide, and 36 inches long, with a weight of 1.83 pounds. Manufactured from AISI A2 tool steel, it offers good dimensional stability during heat treatment and is well suited for applications requiring tight tolerances. Thickness and squareness tolerances are held to plus or minus 0.001 inch, making this bar appropriate for precision tool and die fabrication. Licensed machinists, tool and die makers, and metalworking shops are the primary installers and users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in the fabrication of punches, dies, gauges, and cutting tools across light manufacturing and precision machining environments. A2 air-hardening tool steel is a common choice for toolroom applications where dimensional consistency after hardening is critical. The 36-inch length provides sufficient stock for most toolroom cutting operations without excessive waste. Width tolerance is held to plus 0.000 to 0.005 inch, and length tolerance is plus 0.25 inch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for dimensional stability during hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inch for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inch per inch on all edges\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inch on 36-inch bar\u003c\/li\u003e\n\u003cli\u003eReady-to-use flat stock format reduces pre-machining setup time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat bar suitable for general toolroom and die-making fabrication applications where A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of A2 tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Follow established heat-treatment procedures for A2 air-hardening steel when hardening is required; improper heat treatment can result in distortion or cracking. Wear appropriate personal protective equipment when cutting or grinding. Consult the material data sheet for specific heat-treat parameters before processing.\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 (AISI Type A2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/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: 1.83 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: 54557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541520679218,"sku":"54557","price":185.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_90eabffa-ac6d-4169-a3c4-2484d09b606f.jpg?v=1785878163","url":"https:\/\/voomisupply.com\/products\/starrett-54557-a2-tool-steel-flat-stock-5-32x1x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
