316L Passivation
316L Passivation
(OP)
Hello,
I am trying to find any and all info on the passivation of 316 SS. I would think to use Nitric and H2O but I am not sure. The end use of the product (pipe) will be for hydrogen peroxide service. Is there a standard passivation formula for 316SS regardless of application?
Also, would 316SS even be the ideal material to use?
Thanks for any and all help.

Regarding the resistance of 316l to Hydrogen peroxide if you look in Cor-Sur of NACE you'll find that the Corrosion rate varies between <2 to <20 mpy depending on Concentration and Temperature. So it depends on the concentration, operating parameters and design life of your plant.
Regarding the passivation i've found an interesting article on : ww

Hope this help

It has been many years since I had contact with them but they were very helpful in providing information.

Very good article that you have referenced.

Using stainless in peroxide is another issue. Many metals can be used for peroxide service, but system design is critical.
