Just to point something out here. The hydrogen embrittlement is not a problem with the steel but in the chrome and if not taken care of would flake off even with the smallest rock chip. This is more of a problem in pieces with multiple plating layers. Hydrogen embrittlement of steel would require a molten steel pool without a protective atmosphere or by using a non-low hydrogen process or being careless with the rod ovens. This is also seen in thicker sections like 1" +.
By sticking the parts in the oven you give the hydrogen a chance to diffuse through the matrix and come out of the part thus resulting in less hydrogen pockets, cracks and stress concentrators.
At least that's what I've seen with chrome.
Sorry for the tangent.
I also like the chrome wheels back in nascar.
