AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, NM550 steel chemical composition. The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.
