Passivation

[War118]

Can anyone recommend a product for passivation that I can acquire quickly?
I’m doing some stainless steel welding on Sunday and this is the first time and I’m unsure what product to get.

Thank you.

Have a word with your local welding equipment supplier

Are you going to pickle before passivating? Pickling is a kind of mild etching, that cleans any oxide off the surface. Passivating then re-creates the protective oxide layer which the pickle has probably removed, and the two processes together restore appearance and optimum corrosion resistance.
I used to work in a lab where we blended our own solutions. There was a company (German in origin) in the UK who supplied both products in gel form (which was very handy), I think this them http://www.pelox.de/int/sales/united-kingdom We always regarded their technical advice as the Dog's danglies. Sunday might be a push.
