XAR450 steel is a special structural steel material with high wear resistance. The average hardness of this special wear-resistant structural steel is 450HB, which has high hardness and good toughness. The structure built with this steel is stronger, lighter and can withstand impact loads. XAR450 steel is used for wear parts-exposed structures such as protective pads, shell walls, support and reinforcement plates for excavators, mining machines and bulldozers.
