Duplex 2304 Stainless Steel
Duplex 2304 is a molybdenum-free duplex stainless steel with a balanced ferritic-austenitic structure. It offers corrosion resistance similar to 304L/316L but with nearly double the yield strength. It features excellent stress corrosion cracking resistance, good weldability, and high mechanical strength. Suitable for temperatures from -50°C to 300°C.
