Price : On Request



Duplex S31803, also known as stainless steel grade 2205, is a standardized formulation that conforms to UNS specification regulations. Its temperature range is typically listed as -50° to 300° C (-58° to 572° F); outside of this range, its performance characteristics degrade. Specifically, duplex S31803’s micro-components experience precipitation with prolonged exposure to high temperatures, and ductility suffers from immersion in extremely cold environments.

Its general capabilities include:Excellent oxidation resistanceOutstanding performance in marine/sea water environmentsLow thermal expansion coefficientsHigh heat conductivity
