It measures 18 inches long by 0.5 inches wide by 0.25 inches thick and weighs 0.64 pounds. Type 4142 is a chromium-molybdenum alloy steel known for its high strength, toughness, and wear resistance in the pre-hardened condition. This flat stock is suited for machining, fabrication, and tooling applications where consistent dimensions and tight tolerances are required. Machinists, tool-and-die makers, and metalworking fabricators typically work with this material for fixtures, guides, wear parts, and custom tooling components.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is used in machine shops, maintenance facilities, and industrial fabrication environments. Its pre-hardened state allows it to move directly into machining or finishing operations without additional heat treatment in many applications. The precise dimensional tolerances make it appropriate for close-tolerance tooling, jigs, fixtures, and structural machine components in both light and heavy industrial settings. It is sold in single-piece quantities with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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 ready for machining without additional heat treatment in many applications\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.125 inches ensures consistent oversize stock for finish machining\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.005 inches and thickness tolerance of plus 0.001 inches for precise fitment\u003c\/li\u003e\n  \u003cli\u003eSquare tolerance of 0.003 inches maintains consistent cross-section geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-piece minimum order quantity for low-volume and prototyping needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose pre-hardened flat stock for use in machining, tooling, and fabrication applications requiring AISI\/SAE Type 4142 alloy steel material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting, drilling, and grinding pre-hardened alloy steel requires tooling rated for hardened materials such as carbide-tipped or high-speed steel cutters. Secure the stock firmly in a vise or fixture before machining to prevent movement and maintain dimensional accuracy. Follow applicable shop safety standards when cutting or grinding, including use of appropriate personal protective equipment and coolant where specified by tooling manufacturers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.64 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus 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\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 81173809\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51985448141106,"sku":"81173809","price":51.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_248e5a77-e67d-4a08-bb94-f446f56d1689.jpg?v=1789985427","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81173809-alloy-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
