NM450SP super wear-resistant steel is a special ultra-high strength wear-resistant steel plate with excellent wear resistance and high strength.NM450SP wear-resistant steel distributing large amount of nano-carbide on lath martensite matrix to further enhance wear-resisting property.
The NM450SP wear resistance property is enhanced by the precipitation of super hard TiC particle,its hardness and mechanical property is equivalent to NM450, but its wear resistance is more than 1.6 times of NM450,and 1.3 or more times of NM550.
Purpose:Lining steel of stirring tank;Steel for opening interior liner
Advantages: strong ductility and toughness, enhanced wear resistance
