Corrosion resistance is equivalent to type 304, high mechanical properties and good weldability, work hardening and cold-tough to -110°C.
Dissimilar welding between steel and stainless steel, armor plate, exhaust systems (type 409, 304), high Manganese austenitic steel, difficult to weld steels such as: 42CrMo4, C45, 42MnV7, tool steels, 1.3401, X120Mn12 etc.
