16MnCr5 Alloy Steel Bright Bar
16MnCr5 round steel is a national standard structural steel, similar to the national standard 16CrMnH steel in the national standard GB/T 5216-2004. It has better hardenability and processability. Mechanical parts produced with 16MnCr5 can have larger cross-sections, and higher surface hardness and surface hardness can be obtained after heat treatment. Wear resistance and low temperature impact toughness are also very high. 16MnCr5 gear steel is used after carburizing and quenching. Mainly used to manufacture gears, worms, sealing sleeves and other parts. 16MnCr5 belongs to China's GB standard: Standard: GB/T 3077-1988.
