What are the advantages of NM400 wear-resistant plate?

　　The high-strength NM400 wear-resistant plate is achieved by adding different alloy elements to achieve solid solution strengthening, grain boundary strengthening and second phase strengthening of the matrix structure. It has presented low-alloy martensite steel, bainite steel, and austenite. Duplex/Bainite Duplex Steel, Martensite/Bainite Duplex Steel, etc. In recent years, with silicon as the main alloying element, the use of silicon has strongly suppressed the characteristics of carbide separation during the bainite transformation process.

　　An austenite-biphasic structure composed of carbide-free bainite ferrite and residual austenite stabilized by carbon and silicon can be obtained. Since carbide-free eliminates the cause of cracking or spalling, it has excellent strength The inductive mechanical function of resistance is now the most popular new generation of wear-resistant material in the world, with the following advantages: yield strength, high tensile strength and good ductility.

　　NM400 wear plate has high strength and high fracture resistance; high impact strength; excellent wear resistance. The high-strength NM400 wear-resistant plate has a special heat treatment process. The steel has both high strength and high resistance, and excellent casting processability. Compared with high manganese steel and high chromium steel, the wear resistance is improved by more than 2 times. The ultra-high-strength NM400 wear-resistant plate is alloyed by rare earth transformation, and after a certain process, nano-scale bainite/martensite complex phase structure is obtained.

　　NM400 steel plate has a tensile strength of 1950MPa, an elongation after fracture of 17%, a shortening rate of 38%, HRC55, Aku72J, excellent resistance endurance induction function, extremely strong theoretical research value and use promotion value. The steel has good mechanical processing function, casting function and welding function. After isothermal quenching, the strong plastic product reaches 51GPa%. High strain rate deformation ballistic test indicates.

　　The characteristics of NM400 plates are mainly used in environmental parts such as mines, construction machinery, strong wear and tear; open-pit mine shovel teeth, bucket teeth, excavator factory supporting shovel teeth, etc.; vehicles, iron tracks, power, communications, mechanical equipment , Mining machinery, picks, hydraulic equipment, transmission equipment, high-strength standard parts, etc.; high-strength bolts, wear-resistant wire mesh, steel reinforcement for coastal bridges and high-strength equipment, etc.
