Passivating 400 series stainless steel

(1996)

What is the proper procedure for passivating 400 series stainless steel?

We occasionally experience etching of the material. This is especially a problem with heat-treated 440 series stainless.

Hello, Keith. The February 1988 issue of Metal Finishing magazine has an article by D.K. Verma entitled "Surface Preparation of AISI 400 Series Stainless Steel Components". I think it is well work getting and reading.

Of course, there are alternatives to nitric acid passivation, including electropolishing or citric acid passivation. Good luck.
