Abstract

The invention relates to a surfacing welding wire, in particular to an Inconel 625 modified alloy surfacing welding wire and a preparation method thereof, and belongs to the technical field of anti-corrosion and anti-wear materials. The wire material comprises the following chemical components in percentage by mass: 18.0 to 25.0 percent of Cr, 6.0 to 12.0 percent of Mo, 0 to 3.0 percent of Fe, 0 to 1.0 percent of Co, 0 to 1.0 percent of Nb, 0 to 0.5 percent of Ti, 0 to 0.5 percent of Al, 0 to 0.5 percent of Mn, 0 to 0.5 percent of Si, 0 to 0.2 percent of La, 0 to 0.2 percent of Ce, 0 to 0.1 percent of C and the balance of Ni. The wire has good forging and cold-drawing process properties, the prepared surfacing layer has excellent high-temperature corrosion resistance and wear resistance, and the corrosion resistance, high-temperature oxidation resistance and wear resistance of boilers, especially garbage incinerator boilers, can be greatly improved.

Description

technical field

[0001] The invention relates to a surfacing welding wire, in particular to an Inconel 625 modified alloy surfacing welding wire and a preparation method thereof, belonging to the technical field of anti-corrosion and anti-wear materials. Background technique

[0002] Boilers, especially waste incinerator boilers, use membrane-type water-cooled walls, and many flake tubes form a whole heating surface of the water-cooled wall. The water-cooled wall tube faces the harsh environment of high temperature and flue gas corrosion, so it is very easy to produce erosion wear and high temperature corrosion, which makes the tube wall thin or even wears through, which brings great danger to the safe operation of the boiler. Generally, surfacing Inconel 625 alloy is used to prolong the service life of boiler water wall tubes. The high-quality Inconel 625 surfacing layer has excellent corrosion resistance and wear resistance.
