Is 16MnCr5 forged or cast????

16mncr5 belongs to the European standard "guaranteed hardenability carburizing steel", the implementation standard: 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, and can obtain higher surface hardness and wear resistance after heat treatment for larger cross-sectional parts, and high impact toughness at low temperature. 16Mncr5 gear steel is used after carburizing and quenching, and is mainly used to manufacture gears, worms, sealed shaft sleeves and other parts.

The chemical composition of 16MnCr5 is shown in the following figure:

German standard alloy special steel.

EN steel is a type of alloy steel that is used for primary forming into a forged product. is the EN numeric mark for this material. 16MnCr5 is the EN chemical name.

In EN forged alloy steel, it has a lower embodied energy and a lower base cost. EN steel (16MnCr5 material) is a European standard carburizing steel (case-hardened steel) with good hardenability and machinability. For parts with larger cross-sections, heat treatment results in high surface hardness and wear resistance, as well as high low-temperature impact toughness.

It is equivalent to 15crmn of the national standard, which is malleable.

16mncr5 belongs to a grade of German standard, in the national standard of the material corresponding to 15crmn, it does not seem to be 20crmo, in the market is now this material is relatively small, but Xingcheng, Guigang, Fushun and other steel mills also still have the production of 16mncr5 this material.

16MnCR5 implementation standard EN 10084-1998, is a steel grade imported from Germany, equivalent to China's 16CRMNH steel (refer to GB T 5216-2004), with good hardenability and machinability, for larger cross-section parts, heat treatment can obtain higher surface hardness and wear resistance, low temperature impact toughness is also higher.
