Petrofit Alloys And Engineering LLP is a reliable supplier, dealer and importer of Duplex Stainless Steel UNS S31803 and UNS S32205 (2205) sheets and plates used in highly demanding industrial environments. Duplex stainless steel 2205 is known for its combination of high strength and excellent resistance to corrosion, particularly in chloride-rich environments.
SS Duplex 2205 sheets and plates are widely used in offshore structures, petrochemical plants, desalination systems and chemical processing equipment. The duplex microstructure, which contains both austenitic and ferritic phases, provides improved resistance to stress corrosion cracking and pitting corrosion compared to conventional stainless steels.
For applications requiring extremely high resistance to acidic environments, industries sometimes use SS 904L sheets and plates. However, duplex stainless steel 2205 is often preferred when both corrosion resistance and high mechanical strength are required.
As part of our broader stainless steel sheets and plates supply, Petrofit maintains ready inventory of Duplex 2205 materials in multiple thickness ranges, finishes and dimensions to support fabrication companies, EPC contractors and industrial distributors worldwide.
