Performance characteristics of stainless steel welding wire: In terms of chemical composition, it is usually similar to the base material composition. Molybdenum containing welding wire can enhance its resistance to pitting and crevice corrosion, and some welding wires can improve their high-temperature corrosion resistance by adding elements such as Ti and Nb. In terms of mechanical properties, austenitic welding wire has moderate weld strength and good toughness, while martensitic welding wire has high hardness but high brittleness. In terms of process performance, rutile type flux cored welding wire has small spatter and beautiful forming, while metal powder cored welding wire has high deposition efficiency.
