Material Name: Gear Steel 16MnCr5
Implementation of the standards: EN 10084-1998
● Features and Scope:
Is steel imported from Germany, the equivalent of 15CrMn steel, better hardenability and machinability of the larger cross-section parts, heat treatment can get a higher surface hardness and wear resistance, low temperature impact toughness is also more high. After carburizing use, mainly for the manufacture of gears, worm, sealed bushings and other components.
