CorrosionThe effect of Graphite on the corrosion of Type 316L stainless steel (SS) was investigated in molten FLiNaK (LiF-NaF-KF: 46.511.542 mol.%) salt using electrochemical methods. Results show that Type 316L SS and Graphite, when ohmically-coupled, are susceptible to galvanic corrosion in...
The values of the galvanic current density corresponded to the dissolution rates due to galvanic coupling. Galvanic corrosion of Al alloys coupled to stainless steel decreased in the order Al-5%Mg>Al-5%Ca>99.98%Al>Al-1%Mg>Al-1%Ca>Al-1%Mn>Al-5%Mn. Results of the galvanic anode test showed...

You need to find out why your client is more concerned about galvanic corrosion of carbon steel valves than stress corrosion cracking of stainless steel. Try digging out a materials selection report to establish why your design office colleagues feel that this situation is acceptable. Steve Jones...
This study did not find galvanic corrosion of the welded stainless steel and carbon steel. 展开 会议名称: Mechanics of Structures and Materials: Advancements and Challenges, Volume 1: Proceedings of the 24th Australian Conference on the Mechanics of Structures and Materials.Perth(AU).6-9 December ...
When using two metals together, such as when stainless steel stanchions are installed, you need to ensure the screws/bolts used to secure them are compatible with the stainless. If they are not compatible, the chance of suffering galvanic corrosion becomes very real. Galvanic corrosion occurs whe...

There are some well-known examples of bimetallic (galvanic) corrosion. For example, N-80 couplings connected to J-55 tubing always corrode preferentially to the J-55 grade at fairly rapid rates in wet CO2 environment. Stainless steel valve in cast steel body also create a galvanic couple. Co...
