What does the number in 16MnCr5 mean?

16mncr5 alloy steel, the number indicates the element content

16mncr5 characteristics and applications:16MnCr5 material, German grade special steel. It is equivalent to China's 16CRMNH steel (refer to GB T 5216-2004), which has good hardenability and machinability, and can obtain higher surface hardness and wear resistance after heat treatment for larger cross-section parts, and the low-temperature impact toughness is also higher.

16Mncr5 gear steel is used after carburizing and quenching, and is mainly used to manufacture gears, worms, sealed shaft sleeves and other parts.

It seems to be a question about alloys.

16MnCR5 belongs to the European standard "guaranteed hardenability carburizing steel", which implements the Burning Standards: EN 10084-2008

16MnCr5 is a steel grade introduced from Germany, which is equivalent to 16CrMnh steel in China (refer to GB T 5216-2004), which has good hardenability and machinability. 16Mncr5 gear steel is used after carburizing and quenching, and is mainly used to manufacture gears, worms, sealed shaft sleeves and other parts.
