A. It is very common to blacken stainless steel and brass using black oxide chemistry. This is a conversion coating process that will impart a nice, durable finish. Look in your local business directory for a plating or coating shop near you.

A. Doesn't Prismatic Stainless Steel [from B&M Finishers, a finishing.com supporting advertiser] perform and license an anodizing process for stainless? They are the only ones that I have heard of that developed this process.

You'll love this book. Finishing.com has sold almost a thousand copies without a single return request :-)


A. Anodizing of aluminum is a very widely practiced generic process and the colors are the result of dyes put into the pores; anodizing of stainless steel is done with proprietary processes and the colors are a partial wavelength interference effect like a drop of oil in a puddle; anodizing of steel is not possible to my knowledge.

Q. Dear Sir,

We have some stainless steel meshes for anodizing. We are pretty sure they are "free of Oil or gunk" (washed throughly by weak acid). But we still got "uncoloured spots" after anodizing. We dunno what the problem is.

A. Hi, Sean. I would suspect that the parts are not clean, and it sounds like you suspect that as well. Scrub some sample parts with powdered pumice this on eBay or Amazon [affil links] or Bon Ami this on eBay or Amazon [affil links] before the acid dip and see what you find out. Good luck.

Q. Is it possible to carry out anodizing of heat treated mild steel and how?

A. Hi, Sam. I've expressed my opinion that you can't currently anodize steel ... but the real question here is what do YOU mean?

What operation do you want to do to the steel, or what qualities or properties are you trying to impart to the surface?

Can you put steel parts into a tank and make them anodic -- of course you can. But what you will do to the steel depends on what solution is in the tank, etc., and I don't think there is any accepted thing you can do to it this way that will generally be beneficial :-)
