High molecular wear plate is mainly composed of two parts, low-carbon steel and alloy wear layers, wear-resistant layer is generally the total thickness of 1 / 3-1 / 2. Provide comprehensive performance strength against external forces, such as toughness and ductility at work by the matrix, provide working conditions that meet the specified requirements by abrasion resistant layer. And wear-resistant steel alloy wear layer between the substrate and the metallurgical bond. Through special equipment, automatic welding process, the self-protection of high hardness alloy welding wire evenly on the substrate. Composite layers to two as well as multi-layer composite process due to the contraction ratio of different alloy, transverse cracks appear uniform, which is a distinctive feature of abrasion resistant steel. Also wear layer mainly chromium based alloy, while adding other alloying ingredients manganese, molybdenum, niobium, nickel and the like, carbide fiber morphology, fiber direction perpendicular to the surface. HV1700-2000 carbide micro hardness can reach above the surface hardness can reach HRc58-62. Alloy carbides at high temperature has a strong stability, to maintain a high hardness, but also has good antioxidant properties, completely normal use within 500 ℃.
