The high chromium, molybdenum and nitrogen contents provide better corrosion resistance than 316/316L and 317L stainless steel in most environments. The 2205 is not recommended for operating temperatures above 600¡ãF. 2205 is designed to be significantly stronger than 316/316L, generally allowing for lighter wall construction. 2205 has good notched impact toughness below -40¡ãF. 2205 is welded with E2209 or ER2209 filler.
