The high-strength NM400 abrasion resistant steel plate has high strength and high fracture resistance, high impact strength and excellent abrasion resistance. The high-strength NM400 abrasion resistant steel plate has undergone a special heat treatment process, with 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 abrasion resistant steel plate undergoes rare earth metamorphism alloying, and undergoes a certain process to obtain a nano-scale bainite/martensite composite structure.
The tensile strength of the high-strength NM400 abrasion resistant steel plate reaches 1950 MPa, the elongation after fracture is 17%, and the section shortening rate is 38%. NM400 abrasion resistant steel plate has good machining function, casting function and welding function. After austempering, the strong plastic product reaches 51GPa%.
High-strength NM400 abrasion resistant steel plates are mainly used in mining, construction machinery, strong abrasion and other environmental parts; open-pit mine teeth, bucket teeth, excavator factory supporting shovel teeth, etc.; vehicles, iron tracks, electricity, communications, mechanical equipment, mining machinery, picks, hydraulic equipment, transmission equipment, high-strength standard parts, etc.; high-strength bolts, abrasion-resistant wire mesh, Binhai Bridge steel bars and high-strength equipment, etc.
