Can galvanized shackles be used with stainless steel shackles

When galvanized steel and stainless steel contact for a long time in salt water or salty air, reactive corrosion or galvanizing deterioration will occur.

The degree of electrochemical reaction depends on the proportion of the area. For example, the stainless steel shackle or anchor connector may react with the last link of the shackle, but it is unlikely to have any significant impact on the galvanized anchor.

PPU stainless steel shackle is a more reactive steel than galvanized steel. Reactive corrosion or galvanizing deterioration will occur when galvanized steel plate contacts stainless steel for a long time in salt water or salty air. The degree of electrochemical reaction depends on the proportion of the area. For example, the stainless steel shackle or anchor connector may react with the last link of the shackle, but it is unlikely to have any significant impact on the galvanized anchor.

PPU stainless steel shackle is a more valuable metal than galvanized steel. Galvanic corrosion usually occurs in precious metals. This is a slow process. It can be monitored and monitored before it develops into an ugly or serious problem. For example, it is easy to replace galvanized shackles, and the last link of the chain can be removed with bolt scissors, angle grinder or hacksaw.

These images show what may happen, but it will not help if you do not have a deep understanding of how long the deterioration will take.

It is recommended that the owner immediately cut off the illegal links. Although it is ugly, there is still a lot of metal to bear, but if it is not handled, the problem will further spread to the whole chain. When the chain is not in its original state, the corrosion process will accelerate.

The content of brackish water varies with geographical location. Some areas may be particularly salty and even chemically corrosive to any metal surface. The electrochemical corrosion of precious metals (cathode) occurs in precious metals.
