I can't speak to the question about the oven, but I would think the powder coating would crack and flake off with the flexing of the springs.


Powder coating should be fairly flexible. At least the product I'm familiar with is. However, if the ovens raised the spring temp above 400 degrees f, then temper of the springs could become an issue as many spring steels temper anywhere around 400. 350 and lower,it shouldn't be a problem. Any metallurgists, powdercoaters care to confirm or deny?
