The application of manganese steel 65Mn 70Mn 35Mn 20Mn

Posted:2021-03-18 15:09:06

The manganese steel 15Mn and 20Mn is used to manufacture parts with high mechanical properties and need carburizing.

The manganese steel 25Mn and 30Mn can be used as bolt, nut, screw, lever, brake road plate, and can also be used as small parts under high stress, such as hooks, rings, chains, etc. on agricultural machinery.

The manganese steel 35Mn and 40Mn is used as winter parts under fatigue load, such as roller shaft and screw and nut under high stress.

The manganese steel 45Mn and 50Mn is used to make parts with high wear resistance and heat treatment under high load, such as gear, gear shaft, friction plate and spindle with small section.

The manganese steel 60Mn and 65Mn is usually used as spring, plowshare, etc

The manganese steel 70Mn is usually used as mechanical parts with higher strength requirements.
