Hot Dip Galvanizing reduces strength by 20%?
Hot Dip Galvanizing reduces strength by 20%?
(OP)
Any basis in this claim? I am aware HD Galvanizing can cause hydrogen embrittlement but does it reduce overall strength of 'smaller' steel parts by 20%? By 'smaller' I mean 1/2" to 1" diameter rod or bolts.

depending on the condition of the steel it could temper to a lower strength. The high temperature and following slow cool will bake out ( or reduce to low level ) any hydrogen in the steel

not sure about the percentage of the lower strength will be. But, as for the HDG bolting and nut, some extra material need to be trimmed to accommodate the thick HDG layer. IMO, it may be resulted in the lower strength of the HDG bolting parts.

Hydrogen embrittlement is a possibility, cracking due to picking up Zn in the base material is another one.
This reduces the strength of the base material to zero if cracking occurs. Haven't ever heard of the 20% reduction.
