Treatment on SS 202 for non corrosion

We are using SS 202 Sheets (1.2MM) for our fabrication of equipments. This is done to save the material cost due to very competitive market.

Is there a treatment/solution that makes the surface of the SS 202 non corrosive like the SS 304?

I am told that there is a chemical treatment, but I am yet to find a clue.

Thanks in advance for help.

SS 202 Sheets can be treated with a proprietary Chemical material that will extend the life by making the SS base metal non reactive to corrosive elements.

The System functions by removing selectively the most corrodable material....iron , from the surface without affecting the surface finish and leaving behind oxides of the Nickel and chrome on the surface to protect the SS.

This material comes as a liquid and parts can be dipped in it. It also is available as a brush on material that is washed off after some time. The material itself is very enviro friendly and , Food safe.

This site does not permit proprietary names and addresses so this is all I am permitted to say here.

However I am permitted to state I am a consultant listed on Finishing . com.

What Mr. Asif Nurie has described without naming it is the process called passivation. Given his description he is referring to citric acid based passivation specifically, though nitric acid passivation does also still exist out there.
