Product Description

scm420h 20crmnti Hot rolled steel round bar 

SCM420H,20CrMnTiH is a well-performing carburized steel with high hardenability. It has a hard and wear-resistant surface and a tough core after carburizing and quenching. It has high low temperature impact toughness, medium weldability and machinability after normalizing. good. It is used to manufacture important parts with high-speed, medium or heavy load, impact and friction with a section <30mm, such as gears, ring gears, gear shaft crossheads, etc. It is a substitute steel of 18CrMnTi, widely used as a carburized part. It is used in the automobile and tractor industry for important carburizing parts such as gears. Axis. Ring gear which is subjected to high speed, medium or heavy load and impact and friction. Gear shaft, main shaft of sliding bearing, crosshead, claw clutch, worm, etc.
