Manufactured to AISI\/SAE Type 4142 specification, this chromium-molybdenum alloy steel is supplied in a pre hardened condition, making it ready for tooling, fixture, and die applications without additional heat treatment. It weighs approximately 15.23 pounds per piece. Machinists, tool and die makers, and industrial maintenance professionals use this stock when they need a dimensionally consistent, hardenable alloy bar that holds tight tolerances right out of the box.\u003c\/p\u003e\u003cp\u003eType 4142 pre hardened flat stock is well suited for jigs, fixtures, tooling plates, wear components, and machine parts that require higher strength than mild or medium carbon steel. The pre hardened condition reduces in-shop processing time and is appropriate for both job shop and production environments where consistent material properties are critical. This piece ships as a single unit and is intended for direct use or finish machining to final dimensions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 chromium-molybdenum alloy steel for higher strength and hardenability\u003c\/li\u003e\n\u003cli\u003ePre hardened condition eliminates need for in-shop heat treatment before use\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.125 inches ensures stock is never undersized in length\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches maintains precise lateral dimensions\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 accurate layout and fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose alloy steel flat bar for tooling, fixture, and mechanical component fabrication applications requiring AISI\/SAE Type 4142 pre hardened material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of alloy steel flat stock should be performed by qualified machinists using appropriate tooling rated for hardened steel. Carbide or high-speed steel cutting tools are typically required. Secure the workpiece firmly before any cutting or grinding operation. Consult material safety data for the alloy before grinding, as chromium-containing steel dust requires proper respiratory protection per applicable shop safety standards.\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: 3 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: 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\u003eWeight\u003c\/strong\u003e: 15.23 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: 81175127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51971165520178,"sku":"81175127","price":198.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_f908ca84-a00d-485d-bbab-65ece9f7d11a.jpg?v=1789953947","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-81175127-alloy-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
