Molybdenum disulfide (MoS2) is a popular lubricant, however a study completed in the early 1990’s stated that this type of lubricant can lead to stress corrosion cracking (SSCC) of the bolting materials. However, over the past 20 years, many bolting applications using molybdenum disulfide based compounds have been found to provide better galling resistance to the bolt assembly than many other components. It has also been shown to have a few other less desirable traits such as potential for corrosion in specific environments. Therefore, for successful bolting applications one must consider all the pros and cons of the anti-seize compound they select. One of the negative properties of molybdenum compounds is their link to SSCC on some alloys in specific environmental conditions. This paper focuses on corrosion potential.
