Stainless Steel 316 vs Alum solution

Stainless Steel 316 vs Alum solution

(OP)
Hello Everybody,

In my project , we are using a C channel made of SS 316 ,
this channel is installed in a mixer concrete wall, and immersed in Solution of Water,Alum,Chlorine ...

It is a water pre-chlorination.

After a while , we found that the C channel is very rusty .
Has anyone has any idea about what happened, and how we are supposed to repair it , or what is the coating we are supposed to use..??

Waiting for your replies..
Thanks in advance

Assem

One word Chlorine.
Come back with a little more specifics as to concentration, temperature, and such.

RE: Stainless Steel 316 vs Alum solution

The Outokumpu web site has an excellent corrosion guide. It may help.
 I believe there is a great deal of difference between chlorine dissolved in water and chlorides in water. Which do you have?
