Comprehensive comparative analysis of 16MnCr5 and 20MnCr5 steels
16MnCr5 has good hardenability and machinability, for larger cross-section parts, heat treatment can get high surface hardness and wear resistance, low-temperature impact toughness is also higher. The 16MnCr5 gear steel by carburising quenching use, mainly used in the manufacture of gears, worm gears, sealing bushings and other parts.
20MnCr5 is an alloy structural steel, belongs to the carburised steel, widely used in the manufacture of high-strength and high-toughness mechanical parts. This steel can obtain high surface hardness and wear resistance through carburising and heat treatment processes, while maintaining the toughness of the core.
