What are the advantages of high-strength wear-resistant steel?

High-strength wear-resistant steel achieves solid solution strengthening, grain boundary strengthening and second phase strengthening of the matrix structure by adding different alloying elements. /Bainite dual-phase steel, martensite/bainite dual-phase steel, etc.

High-strength wear-resistant steel has excellent comprehensive mechanical properties of strength and toughness, and is currently the most popular new-generation wear-resistant material in the world.

High-strength wear-resistant steel has the following advantages: high yield strength, tensile strength and ductility; high strength and high fracture toughness; high impact strength; excellent wear resistance.

The high-strength wear-resistant steel has undergone a special heat treatment process, and the steel has both high strength and toughness, and good forging processability. The wear resistance is more than 2 times higher than that of high manganese steel and high chromium steel.
Room temperature mechanical strength Tensile strength MPa: 1950;
Yield strength MPa: 1600;
Elongation%: 17;
Area shrinkage%: 30;
(Notched specimen) Impact value (impact toughness) HRC: Ultra-high-strength wear-resistant steel is alloyed by rare earth modification.

The nano-scale bainite/martensite complex structure is obtained through a certain process treatment. Its tensile strength reaches 1 950 MPa, the elongation after fracture is 17%, the area shrinkage rate is 38%, HRC55, Aku72J, and the comprehensive strength and toughness are good. It has strong theoretical research value and application promotion value. The steel has good machinability, forging and welding properties. After isothermal quenching, the strong-plastic product reaches 51GPa%. High strain rate deformation ballistic test points out.

At a strain rate of 107 s-1, pressure-induced martensitic transformation to e-Fe, hexagonal close-packed structure, and a strength of about 13 GPa. Under ballistic test conditions, the yield strength is about 3.5-10 GPa. Spall strength, an important parameter for designing armor, is around 2 GPa. In the report, the tensile strength of nano-low temperature bainitic steel reaches 2.5 GPa, and the ballistic impact strength is as high as 10 GPa under high strain. Harsh battlefield tests were also conducted.

The characteristics of high-strength wear-resistant steel are mainly used in: mining, construction machinery, strong wear and other environmental parts; open-pit mine shovel teeth, bucket teeth, excavator factory supporting shovel teeth, etc.; Equipment, mining machinery, picks, hydraulic equipment, transmission equipment, high-strength standard parts, etc.; high-strength bolts, wear-resistant wire mesh, coastal bridge reinforcement and high-strength equipment, etc.
