Corrosion resistance and main use environment of 2205 stainless steel pipe:
Compared to 316L and 317L austenitic stainless steel, 2205 duplex stainless steel alloy 2205 has superior performance in resistance to pitting corrosion and crevice corrosion. It has a high resistance to corrosion. higher. Compared to austenitic stainless steel, 2205 duplex stainless steel alloy has twice the compressive strength. Compared to 316L and 317L, the designer can reduce their weight. Alloy 2205 is especially suitable for the temperature range of -50 ° F / + 600 ° F. Under strict restrictions (especially for welded structures), it can also be used at lower temperatures.
Welding Materials and Welding Technology for 2205 Stainless Steel Pipe: ER2209 welding wire and E2209 welding rod are used to weld 2205 duplex steel.
