The bar measures 0.375 inches thick, 1.75 inches wide, and 36 inches long, and weighs approximately 7.69 pounds. A2 tool steel offers good toughness combined with moderate wear resistance and is well suited to applications where dimensional stability after heat treatment is a priority. Thickness tolerance is held to plus or minus 0.001 inches, making this stock ready for precision layout and machining operations without extensive pre-grinding.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, mold shops, and general machine shops for fabricating cutting tools, forming dies, jigs, fixtures, and gauging components. The 36-inch length provides enough material for most single-component applications or allows the bar to be cut into multiple blanks. A2 air-hardening steel is commonly specified when oil-hardening steels introduce too much distortion risk during the hardening cycle. This stock is appropriate for both prototype and production tooling environments.\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 held to plus or minus 0.001 inches for precision fitment\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 from nominal 36 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge all 0.003 per inch maximum\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank suitable for machining into punches, dies, gauges, and precision tooling components where air-hardening grade material 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 toolmakers using appropriate metalworking equipment. Always wear appropriate personal protective equipment when cutting or grinding steel bar stock. Heat treatment of A2 tool steel should follow the material manufacturer's recommended austenitizing and tempering temperatures and should be performed by a qualified heat treater. Secure the workpiece properly before any machining operation to prevent movement.\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: 0.375 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: 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: Edge all 0.003 per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.69 pounds\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: 57346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544505844018,"sku":"57346","price":452.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_723f34ff-87f2-4362-be33-0ddfa8317688.jpg?v=1785928411","url":"https:\/\/voomisupply.com\/products\/starrett-57346-a2-tool-steel-flat-stock-3-8x1-3-4x36in","provider":"Voomi Supply","version":"1.0","type":"link"}
