Manufactured to AISI\/SAE Type 4142 specification, this chromium-molybdenum alloy steel arrives in a pre-hardened condition, eliminating the need for additional heat treatment before use. It weighs 12.69 pounds per piece. Machinists, tool and die makers, and fabricators use this flat stock to produce jigs, fixtures, mold bases, punches, dies, and other tooling components that require a combination of strength, toughness, and wear resistance.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for general-purpose tooling applications in job shops, manufacturing facilities, and maintenance departments. The pre-hardened condition makes it ready to machine directly to final dimensions. Typical uses include guide rails, wear plates, fixture plates, and structural tooling components where through-hardened stock is required. It is appropriate for both light production runs and one-off custom tooling work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI\/SAE Type 4142 chromium-molybdenum alloy steel for strength and toughness\u003c\/li\u003e\n\u003cli\u003ePre-hardened condition  -  no post-purchase heat treatment required\u003c\/li\u003e\n\u003cli\u003eLength tolerance: plus 0.125 inches\u003c\/li\u003e\n\u003cli\u003eWidth tolerance: plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eThickness tolerance: plus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: 0.003 inches for consistent flatness and perpendicularity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose pre-hardened flat stock for tooling, fixturing, and fabrication applications requiring AISI\/SAE Type 4142 alloy steel material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining of pre-hardened 4142 alloy steel requires carbide tooling and appropriate cutting speeds for the hardness level  -  use standard shop practices for hardened alloy steel. Always use appropriate personal protective equipment when cutting, grinding, or machining. Secure the workpiece firmly before any material removal operation.
