Surface heat treatment methods for nm450 steel yield strength

Oxygen (O) is a harmful element in steel such as NM450 steel yield strength. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

The three factors of wear of NM450 wear plate, NM450 steel yield strength are as follows:(1) The relative motion between two objects, no relative motion, no wear.(2) Surface properties of materials.(3) Contact characteristics with another object (including contact mode, force transmission mode, surface deformation, interaction, etc.).
