Stress Corrosion Cracking Control Plans. 3. Copper Alloys

Abstract

Most service failures by stress corrosion cracking (SCC) in copper alloys are caused by the conjoint action of five factors, (1) water, (2) oxygen, (3) tensile stress, (4) alloy composition and structure, and (5) ammonia or perhaps alternatively ammonia-like complexing agents. Sulfur dioxide can also be responsible for SCC in industrial atmospheres. Alloys have been classified in four categories of susceptibility. Examples have been given illustrating the roles of each of the five factors. The model widely believed responsible for most service failures involves the periodic formation and rupture of a film of Cu2O. Mercury and its compounds must be kept away from copper alloys.
