Shop: Protection for Stainless Work
(OP)
What sorts of measures has your shop taken to protect during the fabrication of stainless items?
Things from lifting stainless plate with the crane on down to tool segregation?
Thanks in advance,

In practice this is a hundred different little actions, and a lot of remediation to fix problems.
Read up some and then come back with specific concerns.

Carpet and rubbber to protect from forks on forklifts and rigging when lifting.
Be careful of all shears, brakes, and rolling equipment that has previously been used on carbon or that contains carbon
RE: Shop: Protection for Stainless Work
I have seen entire process units passivated and then tested for residual iron on the surfaces.
This really should me a minimum requirement. Even if the shop is careful they will get iron on the stainless. Good shop paractice will simply prevent it from being too bad.
Do you reall want horror stories?

Carbonaceous material will only hurt if the material is subsequently heat treated while contaminated.
Even iron contamination is mainly a esthetic problem, because it rusts and makess people think the stainless is rusting and therefore defective, which is why we passivate to remove it.

If the deposite is large, like spatter from grinding or welding, then this all happens faster and worse.

That is my understanding as well. Iron/carbon contamination causes pitting big time.

Also, I am currently considering making an H2S gas removal subsystem, using DMEA, which seems better than NaOH for handling and overall effect on the S/S. Probably a small CCE packed-tower would handle it. Any thought or suggestions on this problem?

If you post your question separately with a descriptive subject line, more people will likely read and respond to it.
Good luck!
