DUPLEX STAINLESS STEEL
Alloy 255 is a 25% chromium super duplex stainless steel. Alloy 255 contains a copper addition which provides it with greater resistance to sulfuric acid than other super duplex grades. Because of its duplex structure alloy 255 also offers excellent strength characteristics and resistance to chloride ion stress corrosion cracking.
- High strength
- Chloride stress corrosion cracking resistance
- Lower coefficient of thermal expansion than austenitic stainlesses
- Good sulfuric acid resistance
