Hot rolled technology of nm400 material specification

The purpose of NM400 material specification quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of NM400 material specification. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

Experiments have proved that the outstanding feature of the precipitation-strengthened NM400 material specification, wear-resistant plate in terms of mechanical properties is that the yield strength is greatly improved. For example, the yield strength of the wear-resistant plate after precipitation strengthening treatment reaches 480-8l0MPa, and the yield strength ratio is 0.55-0.56; the wear-resistant plate that uses molybdenum, vanadium, and iron composite alloying, the yield ratio after dispersion strengthening is 0.60- 0.65.
