It is a kind of 9Cr14Mn13-Ni CO2 gas shielded flux cored welding wire for the hardfacing of the valve sealing surface.
The deposited metal of this product is 9Cr14Mn13-Ni chromium steel, and the deposited layer has air quenching characteristics. Generally, heat treatment is not required, and it is a highly compatible surface deposited flux cored welding wire. It is mostly used for hardfacing of carbon steel or alloy steel valve sealing surfaces with working temperatures below 510 ℃. Features: Excellent welding process performance, less spatter, stable arc, easy slag removal, and good weld formation.The deposited metal is high chromium and high manganese austenitic steel，it has good friction resistance, high hardness at medium temperature, good thermal stability, and good cutting performance.
