We use a chemical process for heat tint removal on stainless dairy tube. The machine is called a Surfox 204 and works great with the heavy duty cleaner.

 

What are the issues with using a stainless steel wire brush to remove the heat tint?

 

Try bartender secret you will find it at your local groceries store. Aply to surface and a wet rag then scrub till gone.

I used to use a pickling gel, which is just an acid but I forget which kind. Just put it on with an acid brush and key it sit a couple minutes and rinse it off with water. We had a guy come demonstrate some machine to us that used an electric current and a special wire brush that made tiny little static looking sparks, but did a good job of cleaning. My boss asked me if it would help me speed up fabrication, but I said for the price it wasn't a huge benefit. But in situations where they don't want any mechanical removal of oxidation, it'll probaby work good. You could probably search for it just as good as I could.

If I remember correctly, these go for about $1,500. I saw some videos on YouTube where a guy made his own. It's pretty simple, just a power source and some acid.

 

If you want a texture finish you can use a small sandblaster.

 

Red 3m scotchbrite with Kleen
Strip Aircraft decal and adhesive remover. Works wonders after the weld has cooled.

 

We use Avesta cleaners, picklin gel (hydrofluoric acid),and passivation fluid. The cleaner removes any organic residues them we put on the picking gel key it do is magic (remove the oxidation from the metal), then apply passivation fluid, rinsing with water in between each step.

I passivated with a large Surfox machine at work a few times on some stainless flotation tubes for a customer in Japan that wants all HAZ removed. Was interesting to do, but the fluid is nasty and we had to wear full protective on a hot summer day.
