The surfacing CCO wear pipe is composed of two parts: low carbon steel pipe and surfacing wear-resistant layer.
The thickness of the wear layer is usually 1/3 to 1/2 of the total thickness. According to customer requirements
The wear-resistant layer of the surfacing wear-resistant tube is mainly formed by surfacing welding of Cr28 welding wire, and other alloy components such as molybdenum, manganese, nickel and niobium are added.
The carbides in the metallographic structure are fibrous, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach above HV1700-2000,
The surface hardness of the surfacing layer can reach HRC58-62.
Chromium carbide has strong stability at high temperatures, maintains high hardness, and also has good oxidation resistance, and is usually used completely within 500 ° C.
Features of surfacing wear-resistant pipe:
1. Excellent wear resistance
2. Flat surface and beautiful appearance
3.Easy to process
4. Excellent impact resistance
5. Outstanding welding strength
6. Comprehensive quality control.
7. High cost performance
