Stress-Corrosion Cracking in Nickel-Base Alloy Weldments (14017)
By Dr. David E. Jordan, International Institute of Welding, Montreal 1990. In the spectrum of corrosion-resisting steels and alloys in which nickel is a significant constituent, nickel-base alloys are often preferred because of their resistance to stress-corrosion cracking. Apart from chloride stress-corrosion cracking, which can arise in a municipality of applications in sensitive materials such as austenitic stainless steels, there are media in more specialized applications that require careful choice of nickel alloys and the condition in which they are used, including hydrofluoric and polythionic acids, caustic soda, and molten metals. Data on unwelded materials are included in this review since their performance under stress is related to the characteristics of the welded joints.
