It measures 36 inches long, 3\/4 inch wide, and 1\/4 inch thick, weighing approximately 1.9 pounds. The stock ships in a single piece and is supplied in a pre-hardened condition, making it ready for machining, toolmaking, jig fabrication, and fixture work without additional heat treatment. Tight dimensional tolerances are held throughout: length tolerance of plus 0.25 inches, width tolerance of plus 0.005 inches, thickness tolerance of plus 0.001 inches, and a square tolerance of 0.003 inches. Machinists, tool and die makers, and maintenance professionals working in production or job-shop environments are the primary users of this material.\u003c\/p\u003e\n\u003cp\u003eAISI\/SAE 4142 chromium-molybdenum alloy steel is widely used in industrial and manufacturing settings where strength, toughness, and wear resistance are required. This flat bar format is suited for producing wear plates, gibs, guide bars, keys, brackets, and custom tooling components. It is appropriate for both light production runs and one-off fabrication work in machine shops, maintenance departments, and metalworking facilities. The pre-hardened condition eliminates the need for an in-house hardening operation before use, saving setup time when working on jigs, fixtures, or structural tooling parts.\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 to machine without additional heat treatment\u003c\/li\u003e\n  \u003cli\u003eTight width tolerance of plus 0.005 inches for consistent fitment in close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus 0.001 inches supports precision tooling and fixture work\u003c\/li\u003e\n  \u003cli\u003eSquare tolerance of 0.003 inches ensures dimensional consistency across the cross-section\u003c\/li\u003e\n  \u003cli\u003eSingle-piece quantity with a weight of 1.9 pounds  -  easy to handle and inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard flat bar stock for general metalworking, toolmaking, and fabrication applications requiring AISI\/SAE Type 4142 pre-hardened alloy steel in a 36 x 3\/4 x 1\/4 inch profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis material is typically cut, drilled, ground, or milled by machinists and tool and die makers using standard metalworking equipment.
