It measures 18 inches long by 10 inches wide by 0.5 inches thick and weighs 25.38 pounds. Type 4142 is a chromium-molybdenum alloy steel known for its high strength, toughness, and good machinability in the pre hardened condition. This flat stock is supplied with controlled tolerances: plus 0.125 inches on length, plus 0.005 inches on width, plus 0.001 inches on thickness, and a squareness tolerance of 0.003 inches. It is a working material for tool and die makers, machinists, and metal fabricators who require a ready-to-machine alloy steel blank without additional heat treatment.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for industrial and commercial fabrication applications including jigs, fixtures, tooling plates, die components, machine components, and structural parts that require higher strength than standard mild steel. The pre hardened condition allows machinists to cut, drill, and mill directly to final dimensions without post-process hardening in many applications. It is a practical starting blank for low-to-medium production tooling and heavy-duty mechanical parts across manufacturing and metalworking shops.\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  -  ready to machine without additional heat treatment in many applications\u003c\/li\u003e\n\u003cli\u003eControlled length tolerance of plus 0.125 inches for consistent stock sizing\u003c\/li\u003e\n\u003cli\u003eTight width tolerance of plus 0.005 inches and thickness tolerance of plus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of 0.003 inches for dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eSingle piece per package  -  no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose pre hardened alloy steel flat stock blank suitable for tooling, fixturing, die making, and structural fabrication applications requiring AISI\/SAE Type 4142 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMaterial cutting and machining should be performed by qualified machinists using appropriate tooling rated for hardened alloy steel. Standard shop safety practices apply including eye protection, secure workholding, and proper chip management. Welding pre hardened 4142 alloy steel requires preheat procedures to avoid cracking  -  consult applicable welding codes and material data sheets before any welding operation. Do not attempt to re-harden or re-temper this material without reference to certified heat treatment specifications.\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: 18 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 25.38 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\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: 81174674\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52023856202034,"sku":"81174674","price":416.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_32747232-b179-4d71-b9dc-a2d527c50bd5.jpg?v=1790014337","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81174674-4142-alloy-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
