316Ti 1.4571

UNS S31635

Alloy 316Ti (1.4571) is similar to 316L, but offers better high temperature strength and mechanical properties. The addition of titanium reduces the risk of intergranular corrosion as carbon preferentially forms titanium carbo-nitrides preventing the formation of chromium carbides in the temperature range of 800 °F to 1,500 °F. This alloy exhibits inferior pitting and stress corrosion cracking resistance compared to 316L, but is considered to have similar general corrosion resistance.
