Low carbon content can reduce the precipitation of carbides in the welding process, so as to maintain the corrosion resistance of the welding structure. This nickel alloy is resistant to the formation of grain boundary precipitation in the HAZ, so it is suitable for most chemical process applications under welding conditions.
