This piece measures 18 inches long by 14 inches wide by 0.375 inches thick and weighs 26.65 pounds. Type 4142 chromium-molybdenum steel is supplied in a pre-hardened condition, delivering improved strength, toughness, and wear resistance compared to mild steel flat bar. It is ready for secondary machining, grinding, or fabrication without requiring additional heat treatment for most tooling and structural applications. Machinists, tool and die makers, and fabricators work with this material in job shops and industrial manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for applications demanding higher strength than standard low-carbon steel, including die plates, fixture components, machine parts, jigs, and structural tooling inserts. The pre-hardened condition makes it appropriate for short-run tooling, wear plates, and precision machined components where dimensional consistency is critical. The piece is sold as a single unit and is intended for professional machining and fabrication use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 chromium-molybdenum alloy steel, pre-hardened for improved strength and toughness\u003c\/li\u003e\n\u003cli\u003eReady for machining and grinding without additional heat treatment for most applications\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.125 inches ensures consistent minimum length\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches for predictable stock allowance during machining\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus 0.001 inches for tight dimensional control\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of 0.003 inches supports precise layout and fixturing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose pre-hardened alloy steel flat stock for tooling, die making, and fabrication applications requiring AISI\/SAE Type 4142 chromium-molybdenum material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis material is intended for use by qualified machinists and fabricators familiar with alloy steel cutting, grinding, and milling operations. Always use appropriate cutting fluids and tooling rated for pre-hardened alloy steel to avoid premature tool wear. Secure the workpiece properly in a vise or fixture before any machining operation. Personal protective equipment including eye protection and gloves is required when cutting or grinding steel stock.\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\u003eCondition\u003c\/strong\u003e: Pre-Hardened\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: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 26.65 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: 81174476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51976877539634,"sku":"81174476","price":298.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_3ad7cbec-d8a8-40d2-9fcc-f6c9f34d6c85.jpg?v=1789979131","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81174476-flat-stock-4142-alloy","provider":"Voomi Supply","version":"1.0","type":"link"}
