What are the advantages of high strength wear resistant steel

By adding different alloy elements, high strength wear resistant steel can be obtained, so as to realize solution strengthening of matrix structure, grain boundary strengthening and second phase strengthening. Using silicon as the main alloying element, silicon can be obtained from carbide-free bainitic ferrite. The use of silicon strongly suppresses the precipitation of carbide during bainite transformation and is stabilized by carbon and silicon. Because it eliminates the causes of carbide cracks or spalling, it has excellent tough mechanical properties and is a very popular wear-resistant material.

High strength wear resistant steel has excellent yield strength, tensile strength and ductility, high strength and fracture toughness, high impact strength and excellent wear resistance. After special heat treatment, the high strength wear resistant steel has high strength, good toughness and good forging processability. Its wear resistance is more than 2 times higher than that of high manganese steel and high chromium steel. The high strength wear resistant steel is transformed into the bulk multiphase structure by a certain process. Its tensile strength is 1950 MPa, elongation after fracture is 17%, area shrinkage is 38%. The comprehensive properties of toughness is very good, which has great research value and application value.
