It measures 18 inches long, 3-1\/2 inches wide, and 5\/16 inch thick, with a finished weight of 5.55 pounds. The pre hardened condition means no additional heat treating is required before machining or fitting to specification. This flat stock is used by machinists, tool and die makers, and metalworking professionals who need a ready-to-use material with controlled dimensional tolerances. Tight tolerances on all four faces make it suitable for precision fixture components, machine parts, jigs, and tooling applications where dimensional consistency is critical.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for industrial and commercial fabrication shops, machine shops, and maintenance departments. It is commonly used to fabricate wear plates, support brackets, die components, and structural machine parts that require moderate to high strength. Its pre hardened state makes it a practical choice when lead time and post-processing steps need to be minimized in a production or maintenance environment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 alloy steel for reliable strength and machinability in the pre hardened condition\u003c\/li\u003e\n\u003cli\u003eDimensional tolerances held to +0.125 inches on length, +0.005 inches on width, and +0.001 inches on thickness\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of 0.003 inches ensures consistent flatness and squareness across the bar\u003c\/li\u003e\n\u003cli\u003ePre hardened condition eliminates the need for additional heat treatment before use\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity allows purchase of exactly the quantity required\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 use in machining, fabrication, and tooling applications where AISI\/SAE Type 4142 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, drilling, and grinding operations should be performed with tooling rated for hardened alloy steel stock.
