The ability of molybdenum to form ferrite is comparable to that of chromium. Molybdenum also promotes intermetallic compounds in stainless steels. In order to maintain a single austenite structure in austenitic stainless steel, the content of nickel, nitrogen, manganese and other austenite forming elements should be increased with the increase of molybdenum content in steel.

Recently, due to the 8-month Russia-Ukraine conflict and the coming winter, the European energy crisis has been intensifying. Natural gas prices in many places have reached record highs, and LNG ship freight rates have continued to rise. Experts say the situation may be worse next year.

Use diamond cone or quenched steel ball indenter to press the indenter into the material surface under the action of test pressure F. After holding for a specified time, remove the main test force and maintain the initial test force. Calculate the hardness value with the residual indentation depth increment. During actual measurement, the Rockwell hardness value can be directly read out through the dial of the testing machine.
