Steels having austeno‐ferritic structure are highly resistant to stress corrosion cracking in the welded as well in the nonwelded condition. It has not been possible in laboratory experiments–calcium chloride solution at 100 °C, with and without anodic polarisation, and chloride containing media at 225 °C – to produce cracking. Crack formation which in exceptional cases may occur in the welded condition may be suppressed by the use of electrodes yielding a weld seam having the same composition as the base material.
