Peculiarity
The weld microstructure is austenitic ferrite biphase structure, which contains about 40% ferrite.
The fused metal has the comprehensive properties of austenitic and ferritic stainless steel, with excellent pitting and stress corrosion resistance.
The arc is soft and stable, less splash, beautiful forming, good slag removal, stable wire feeding, with excellent welding process performance.
