XAR 400W 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. It is heat resistant up to 400 deg C. This datasheet provides information on composition and physical properties. It also includes information on wear resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-836. Producer or source: ThyssenKrupp Steel Europe AG.
