Case Hardening Steel 16/20 MnCr5

Case hardening, also known as surface hardening, is a heat treatment process that involves increasing the hardness of the surface of a metal while maintaining a tough and ductile core. The term "16/20 MnCr5" might refer to the case depth achieved through the case hardening process, where "16" indicates the depth of the hardened layer in millimeters and "20" indicates the total case depth in millimeters.

In summary, case hardening steel 16/20 MnCr5 refers to a low carbon steel that has undergone a case hardening process to achieve a hardened surface layer with a depth of 16 millimeters and a total case depth of 20 millimeters. This type of steel is valued for its combination of hardness, wear resistance, and toughness, making it suitable for a variety of demanding engineering applications.
