duplex plate 4×8 duplex sheet 1.4462 plate
In general, duplex steel S31803 plate can be used as a replacement for the rather expensive stainless steel alloy grade 904L, as 2205 SS plate has similar properties but is less expensive in composition.
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.
