XAR 450 Premium is a special wear-resistant structural steel as thick plate that is water quenched and tempered. These wear resistant materials last at least five times longer than conventional steels due to their extreme hardness and toughness. This datasheet provides information on composition, microstructure, hardness, and tensile properties. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SA-833. Producer or source: ThyssenKrupp Steel Europe AG.
