The wear-resistance of the wear-resistant steel is enhanced by the precipitation of superhard TiC particles. Its hardness and mechanical properties are equivalent to those of NM450, but the wear-resistance is 1.6 times greater than that of ordinary NM450 and 1.3 times greater than that of NM550. GONMO Steel has successfully completed the task of “Industrial production of domestic extreme thin-gauge (4 Å~2000mm) NM450SP” in the ” 13th Five-Year” national key research and development project, which has advantages of strong plastic toughness and improved wear-resistance.
