Have a double anchor setup with Bruce and a CQR. Will likely dump the CQR; Make Bruce #2 and a Rocna #1. My question was about effecting the temper of the steel in an anchor if you regalvanize it.

Ted I've heard that re-galvanizing hardened chain like G4 will weaken it a little. That makes sense to me as it would have to get pretty hot in a bath of molten zinc.

I would be more worried about your plan to cut, twist and re-weld a link. The twisting will work harden it and possibly induce small cracks.

What kind of chain do you have?

Good point but I wonder if really true about regalvanizing.

I would think the original chain would have t be hardened/annealed before hot dip galvanizing the first time...so I'm not sure a second time would have any affect beyond the first.

The melting point for steel is up over 2500 degrees and zinc is below 800.

Interesting...a quick check didn't reveal the answer but maybe someone has the background or link (no pun)....

From what I've read, regalvanizing chain is commonly done. The process requires a tumbling basket to keep the chain from sticking together. Would assume if there was the possibility of the chain loosing significant strength, the galvanizer wouldn't do chain for liability reasons.

Hopcar: I don't know which type of 3/8 chain I have. Haven't gotten to that project yet.

A minimum of 1400-1500 degrees Fahrenheit is required to anneal steel if it is high carbon steel(1650 for low carbon steel). With a melting point of just under 790 degrees hot dip galvanizing will have no ill side effects.

Thanks, that's what I was looking for!
