Alloy S31803 and Alloy S32205 Stainless Steel is used most often in heat exchangers, marine construction, oil and gas industry, chemical processing.
Alloy S31803 and S32205 stainless steel is a dual-phase stainless steel whose grain structure is ferritic and austenitic, hence the name "duplex". With twice the mechanical strength and corrosion resistance of common austenitics, alloy S31803 and S32205 stainless steel offers some advantages over 316L and 317L:
- Lower coefficient of thermal expansion and a higher thermal conductivity
- Resists chloride stress corrosion cracking
- Pitting and crevice corrosion resistance
- Excellent choice for high chloride environments
- Lower cost than high alloyed austenitic
