Excellent resistance against oxidizing media combined with high mechanical strength at room temperature but also at extreme high temperatures combined with high ductility due to the high chromium content. Alloy 690 was developped to offer greater resistance to stress corrosion in the nuclear industry, pure water invironment. Similar to FM 52 but the 52M is for nuclear application where a specific (very strict) chemical analysis is requested.
