65 what is the hardness of the best heat treatment of manganese steel strip?

Answer:

65, the best heat treatment hardness of manganese steel strip depends on the application and heat treatment methods, such as the general in 45~50HRC, general heat treatment at 48 degrees, the best comprehensive mechanical properties.
65 manganese spring steel best heat treatment hardness, mainly to have good elasticity, in the dynamic load environment conditions, there is a high yield strength. In case of heavy load, there should be high fatigue strength. Under repeated loads, it has a long service life, and has sufficient toughness and plasticity to prevent sudden brittle fracture under impact. 65 the best heat treatment hardness of manganese steel strip is HRC48, and the above comprehensive mechanical properties are the best.
65, the optimum heat treatment hardness of manganese strip depends on the application and heat treatment method;1, 65Mn strip at 850 degrees Celsius, quenching oil +180 degrees, low temperature tempering 6 hours, hardness can reach HRC56 or so.2, if it is 400 degrees Celsius, tempering 4 hours, its hardness is generally around HRC39.
