1.4362
Data sheet material 1.4362
X2CrNiN23-4
Lean duplex steel
Brief description
The material 1.4362 or UNS S32304 is a duplex steel with good resistance to general corrosion and stress corrosion cracking. Due to its high yield strength, this material provides twice as high calculation parameters as, for example 1.4301 or 1.4404, This results in a large potential for wall thickness savings.
