An overview of austenitic and ferritic stainless steels

Ferritic Stainless Steels (400 Series) About 20 percent of all stainless steel grades have a ferritic microstructure, with SS430 being the most widely used. SS409 has lower chromium and, therefore, reduced resistance to corrosion. SS439 has greater resistance to corrosion and improved high-temperature stability.Hybrid laser-MAG welding API 5L grade, and wall thickness Hybrid process Welding speeds 2 WM 3 porosity content Hardness, HV5 Parent WM 3 HAZ 4 WM 3 HAZ 4 X60, 15.9mm Nd:YAG-MAG 1 0.9m/min 0.4% 164-204 X60, 15.9mm Nd:YAG-MAG 1 1.0m/min-1.7m/min 0.3% - X80, 16.0mm Nd:YAG-MAG 1 1.0m/min-1.7m/min 0.3% -
