Can Stainless Steel Flanges Match With Carbon Steel Nuts?

First, it is determined by the working environment, the general working environment allows combined use, but they cannot be applied together in the corrosion work conditions.

Second, the carbon steels or alloy steel bolts often match with carbon steel nuts, but rarely use stainless steel bolts or stainless steel flanges, unless the carbon content in the carbon steel of equipment is higher than stainless steel bolts, otherwise it will cause potential difference and electrochemical corrosion. Despite of some special requirements, the fasteners are made of carbon steel, and the material is not in contact with the bolts.

 

Third, the problem is that stainless steel bolts and stainless steel rivet nuts will be thoroughly sticking if in a poor connection, you need to smear the molybdenum trichloride if loosen bolts and nuts, but the lubricant is very expensive. The stainless steel flange is not suitable with carbon steel fasteners, it will cause carburizing corrosion. At the same time, in the applications of flanges, not use with carbon steel fasteners as well.
