Duplex Stainless Steel S31803 (2205) Material

Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation. While the duplex-grade family includes a wide range of specific formulations, duplex S31803 (2205) stainless steel are of the most common.

 

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 with immersion in extremely cold environments.

Duplex S31803 (2205) material is used in applications where high corrosion rates are expected. Duplex S31803 (2205) material products also stand against localized corrosion and pitting as a result of the addition of chromium. This quality makes them have a comparatively larger tensile strength to thickness over austenitic steel types. Therefore Duplex S31803 (2205) stainless steel material is used in applications where weight has to be reduced yet strength cannot be compromised.

Stainless Duplex S31803 material is widely used in chemical industries, marine tools and equipment, water desalination plants, food sector, paper and pulp industry and much more applications.
