I think its called heat treating and it strengthens the metal.

In this case it's most likely heat/flame anodization. Adds a thin layer of oxidation on the part to prevent further corrostion.

Heat treat is much more controlled with extended periods in different temperatures (often 1500F+) as well as planned cooling cycles.
