Typical Job In The Shop

[Ray C]

When I worked in a grinding shop we'd dip tools into muriatic acid to remove bluing. Does that not work for stainless?

I don't know but it probably does. The staining is just a slight oxidizing from air/oxygen burning-off at the surface of the hot part. It buffs off easily. It takes an awful lot to cook and damage stainless steel. It's the predecessor material to Inconel (mainly chrome and nickel) which can take a tremendous amount of heat abuse. I've experimented with stainless by cooking it with the TIG unit. It goes from yellow, to brown, to blue, to dark grey and back to brown again. Once it hits that dark grey color, it's probably not to be trusted for anything important.
