Steel Spring, Zinc Plated, Hydrogen Embrittlement




Presently making a spring(4340, R/C 43-45)that is Zinc-plated. The process calls for a bake subsequent to the plating process to reduce hydrogen embrittlement. Is this step necessary on a spring with a cross-section of .340" x .960"?

Yes spring steel requires baking as soon as possible after plating.

The bake is only required if you do not want a high number of failures. So, is it really required? That is your decision.
