Our 2B finish duplex 2205 sheets combine high strength, low thermal expansion, and excellent resistance to pitting and crevice corrosion, making them ideal for chemical tanker inner linings.

Chemical tankers using 316L stainless steel experience rapid pitting from organic acids and chlorides, plus weight inefficiency due to lower strength properties.

Duplex 2205 provides twice the yield strength of conventional stainless steels, enabling thinner, lighter tank walls. The 2B smooth finish prevents chemical adhesion and simplifies cleaning operations.

• Chemical tanker cargo tanks
• Baffles
• Piping systems
• Manway covers

The high molybdenum (3%) and nitrogen (0.15%) content forms a stable passive film. The duplex microstructure resists stress corrosion cracking under cyclic loading conditions.

Select 2B finish for internal linings requiring smooth surfaces. Choose No.1 finish for structural supports. Ensure compliance with IMO chemical carrier regulations and standards.
