Corrosion for Steels

[nonsinusoidal]

Can you please advice on the type of steel that can be exposed to a wet environment and not corrode as easily as other type of metals?

These are the options I am currently looking into:

1. Hot Dip Galvanized Steel

2.Stainless Steel

Please advise

Hi nonsinusodial

Well stainless steel grade 316l is good for corrosion resistance without any covering, however it also depends on the wet enviroment the steel is in and also how and what it is connected to.
If you put stainless with ordinary carbon steel in a wet enviroment you can set up electrolytic corrosion.
Galvanising ordinary steel is good too and possibly cheaper than stainless can you tell us a bit more about what your trying to do.

I am looking into the type of uni-strut supports which can be utilized in transformer rooms and underground electrical vaults. The uni-strut supports will be mounted on the concrete walls to support electrical equipment. However, the electrical vaults and transformer rooms will be subjected to some water running on their walls. As a result, I am not sure if stainless or hot dip galvanized steel is the appropriate type of material for the uni-strut supports. Please advise and thank you

Hi nonsinusoidal

I think the galvanised steel would be okay.

I would agree, hot dip galvanized is the better selection for this type of environment.
