What are Duplex 2205 UNS 31803 Coils? Duplex 2205 UNS 31803 is a high-performance stainless steel alloy, primarily composed of a mix of austenitic and ferritic structures. This unique composition gives Duplex 2205 its exceptional strength, excellent corrosion resistance, and higher stress and pressure tolerance. It’s particularly known for being twice as strong as the conventional 304 stainless steel.

  • Exceptional strength and durability
  • Excellent resistance to pitting and crevice corrosion
  • High resistance to stress corrosion cracking in chloride environments
  • Superior weldability and formability
  • Enhanced resistance to high-temperature environments
  • Long service life with minimal maintenance in harsh conditions

Working Mechanism

How Duplex 2205 UNS 31803 Works

Duplex 2205 functions by balancing its ferritic and austenitic microstructure, which contributes to its superior mechanical strength and excellent resistance to stress corrosion cracking, especially in chloride-rich environments. The high chromium content forms a passive oxide layer, providing the material with a protective barrier against corrosion. The alloy’s high molybdenum content further enhances its resistance to pitting, crevice corrosion, and general corrosion, particularly in acidic environments.
