Product Description
UNS S32050 is a high corrosion resistant super austenitic stainless steel characterized by its elevated content of nickel (20-23%), chromium (22-24%), and molybdenum (6.0-6.8%). This premium alloy is designed to withstand severe corrosion environments, particularly those involving high-temperature seawater and concentrated chloride solutions. It offers an excellent balance of corrosion resistance comparable to nickel alloys and pure titanium, but with greater economic efficiency. At FUSHUN METAL, we supply UNS S32050 in various forms to meet diverse industrial requirements for applications demanding exceptional corrosion resistance in challenging environments.
Applications
UNS S32050 super austenitic stainless steel is specifically designed for applications that demand exceptional corrosion resistance in aggressive environments:
- Seawater Environments:Seawater desalination systems, seawater heat exchangers, condenser tubes
- High Concentration Chloride Environments:Pulp and paper plants, various types of bleaching systems
- Chemical Processing:Equipment handling aggressive chemicals, storage tanks, and reaction vessels
- Oil & Gas:Offshore platforms, subsea equipment, and components exposed to corrosive conditions
Standards
UNS S32050 conforms to the following international standards:
- American Standard:ASTM A240 (UNS S32050)
- European Standard:Comparable to EN 1.4466 (slightly different composition)
- Japanese Standard:Proprietary high-performance stainless steel grade
