Electro Plating A193 Studs
Can ASTM A193 studs and bar stock be electro plated for corrosion resistance without strength reduction?

High strength steel can be electroplated without strength reduction, but it needs a baking process afterwards to relieve hydrogen embrittlement. Alternately, it can be mechanically plated, or protected with a zinc-rich dip-spin coating. It seems, though, that ASTM A193 describes a wide range of classes, the metallurgy being different for each class. It is possible, I suppose, that one or more classes might be impractical to electroplate. But if you give us the class you have in mind, hopefully someone will have experience in that particular composition.
