It measures 36 inches long, 10 inches wide, and 1 inch thick, and weighs approximately 101.52 pounds. This flat stock is supplied in a pre hardened condition, making it ready for applications that require consistent hardness and strength without additional heat treatment. Machinists, tool and die makers, and industrial fabricators work with this material for the production of dies, fixtures, shafts, machine components, and structural tooling where high-strength chromium-molybdenum alloy steel is specified.\u003c\/p\u003e\u003cp\u003eAISI\/SAE 4142 alloy steel is a chromium-molybdenum grade recognized for its high tensile strength, good toughness, and favorable machinability in the pre hardened state. This flat stock is suited for heavy-duty industrial and manufacturing environments where precision dimensions and tight tolerances are required. Typical applications include die plates, wear components, machine bases, tooling supports, and structural fabrication in machine shops and industrial production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 chromium-molybdenum alloy steel for high strength and toughness\u003c\/li\u003e\n\u003cli\u003ePre hardened condition eliminates the need for post-purchase heat treatment\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.25 inches for positive material allowance\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of +0.005 inches for close dimensional control\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +0.001 inches for precision fit in tooling applications\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of 0.003 inches for consistent flatness and squareness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use pre hardened flat stock for industrial tooling, die making, fixture building, and structural fabrication applications that call for AISI\/SAE Type 4142 alloy steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining should be performed with tooling rated for pre hardened alloy steel. Standard metalworking and fabrication safety practices apply, including use of appropriate personal protective equipment and machine guards. Welding pre hardened 4142 alloy steel requires proper preheat and post-weld heat treatment procedures per applicable welding codes to avoid cracking. Consult a qualified metallurgist or welding engineer before any welding operations on this material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI\/SAE Type 4142 Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 101.52 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: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81177131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52062779834674,"sku":"81177131","price":1262.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_52159a18-5897-4ac7-96d6-fe90a8c0474e.jpg?v=1790042750","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81177131-alloy-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
