Features and Scope: the good performance of case-hardened steel, high hardenability, after carburizing hard and wear-resistant surface and tough core part has a high low temperature impact toughness, weldability medium is good machinability after the fire. For the manufacture of cross-section <30mm withstand high-speed, medium or heavy load, impact and friction parts such as gears, ring gear, gear shaft cross head.
18CrMnTi the generation of steel, widely used as a carburizing parts, automobile and tractor industries for cross-section below 30mm, to withstand high-speed or heavy duty as well as by the impact. Friction carburizing parts such as gears. Axis. Ring gear gear shaft slide bearing spindle. crosshead. claw clutch. worm and so on.
