EN 10149-2 S700MC equivalent, NM400 wear plate is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance. The average hardness of NM400 wear plate is 400HB. After quenching, or quenching and quenching, NM400 wear plate has a good martensite-bainite microstructure. The addition of molybdenum, nickel, and boron alloys ensures uniform texture throughout the thickness direction.

The steel such as en 10149-2 s700mc equivalent delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

Quenching Improve the hardness of en 10149-2 s700mc equivalent steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of en 10149-2 s700mc equivalent steel and comprehensive mechanical properties.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
