Stainless Steel Corrosion
Stainless Steel Corrosion
(OP)
It has been brought to my attention recently that lack of oxyen can cause ss to corrode as quickly as bare carbon steel.....I had always assumed that ss was the way to go in a potentially corrosive atmosphere...this issue came up with a coleague who is anchoring a system underground(soil) and was considering using ss hardware.....has anyone encountered this issue?...thanks

They buried metal samples in trenches.
The dug one up recently after about 40 years.
Corrosion in soils can be very tricky. organic content, salt content, microbes, water, all play a roll in how corrosive the environment is.
In general low alloy SS grades, 410, 420, 304, 316, 201; are not suitable for unprotected burial in soils.

be careful with stainless steel connected to carbon steel, you will have galvanic potential at the connection which can cause the corrosion. you need to avoid connecting dissimilar metals.
