CORROSION COMMENTARY

Abstract

STRESS CORROSION CRACKING. A NEW theory which may explain the phenomenon of stress corrosion cracking in metal structures, has been put forward by Dr. Earl A. Gulbransen, advisory chemist at Westinghouse research laboratories in Pittsburgh, U.S.A. We understand that it is based on the discovery that minute crystals resembling delicate plates tend to grow from the surface of stainless steels when the metal is stressed and exposed to corroding atmospheres. Specifically, the newly discovered crystals are described as ‘sub‐microscopic platelets of chromium oxide,’ and they form on strongly stressed stainless‐steel specimens which are exposed to atmospheres containing traces of negatively charged chlorine atoms (i.e. chloride atoms).
