Most of the time when I heated steel up and bent it I ended up with a blueish tint to it. I never found a way around the change other than paint, maybe heating up a larger section may help blend the color difference or possibly some oil would change the color if you were going for a unfinished look.

Just curious what you are doing... Are you just using an accetaline torch to heat or are you using something like a forge?

using a propane forge I made to just add texture to steel for furniture. I think the reddish hugh comes from getting it too hot. this has been a while new learning process as it is as little different thank just cutting and welding
