NM400 steel is a high-strength wear-resistant steel plate. It has quite high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; NM400 steel plate can significantly improve the wear resistance of mechanical related parts; therefore, it can increase the service life of machinery and reduce production costs. NM400 wear-resistant steel plate is mainly used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

A573 Gr 70 structural steel,There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.A573 Gr 70 structural steel
