What is the black coating on steel?
July 29, 2008
Hello, I am trying to re-create that standard coating that comes on typical steel.
It looks like a transparent lacquer-type finish that is dark grey...
Does anyone know how to apply that to untreated steel in a DIY fashion?

Sorry, Tom, I don't recognize the coating you are referring to. Can you name a particular item that you've seen it on?

Sounds like mill scale that has been oiled at the rolling plant. If so, you can not really duplicate it.

Can too!
Heat it to cherry red, quench in oil.
Fire scale should build up nicely. It's all dependent on the size of what he's working with.
