China Chain Quality
Is anyone using anchor chain made in China. Have concerns about galvanizing but it is half price of American made?

I just went with 300' feet of Titan (CMP)chain from fisheries up here in PNW. Galvanizing looks good but only time will tell. The boat had this chain originally and the PO said it was over 10 years old and was used a fair amount and it still looks halfway decent. I'll check in after 6 months. After doing a hard search the CMP stuff is used as anchor chain all over the world with success, fisheries swear by it and from what I have been reading the acco stuff is a crap shoot when it comes to its galvanizing as well. At around $700 out the door for 300' of 5/16", not to shabby...

Re: China chain quality
Galvanizing could be the least of your worries with generic Chinese chain.

Re: China chain quality
-The first step in galvanizing is making sure the steel is sound ( not diluted with other metals, "no pot metal as we said in the old days!") Not much you can do to control that step other than going for the good reputation of the manufacturer.
-Then the steel has to be acid clean. This step is crucial and if not done properly, will not allow the zinc to stick properly.
-After that the amount of zinc in the coating is the same no matter what. Leaving it longer in the molten zinc does not increase the amount of zinc in the finish product. So the first two steps are the crucial ones. So yes it can make a difference where the chain was produced and galvanized.

FWIW based on what I have seen in my day job, I would not trust third world metallurgy. Many of these folks are barely living... Do you really think they care if the chain is properly forged or galvanized??

Re: China chain quality
More would be known if someone could scrap off a small section of the galvanizing and have a Rockwell hardness test done on one of the links.

Re: China chain quality
Cheating on chain and wire is nothing new, substandard wire was supplied even for the cables on the Brooklyn Bridge. And made in the USA.
But China, these days? Anchor chain is like a parachute, don't buy one from the cheapest stranger. You just don't know, and who wants to spend the money on shipping before you can even test it?

Nah! Ninety-nine out of every 100 links are fine. What are the chances of a bad weld coming between you and your anchor?

Depends on how many feet of chain you have out. Lets see. Most chain is more or less 10-12 links/ft. Call it 10 for easy calculation. If you have out 100' of chain then if evenly distributed you would only have 10 bad links between you and the anchor. Now that's Russian Roulette.

The CMP chain is proof tested and marked. Should be all good with at least that brand

Camp chain? Are you referring to Campbell or CMP?

Yes, annoying autocorrect. For work I use a lot of terms and words that aren't in the dictionary and sometimes have to fight with it. Some devices I can't figure out how to make it leave my spelling alone. Hate technology that thinks it knows more about what I want than I do.

ROFLMFAO.... That depends on who the proctor is for the test and if the proctor has the real world ability to fail a specimen

Did not take me long on these boards to get fed up with this kind of Sinophobia. You could just as easily say "don't buy American because they're all fat and they sue you all the time".
It's like this: a Chinese product can be as well made, environmentally friendly and ISO compliant as any USA made product.
Worldwide, there is a desire for product that are made as cheaply as possible - simply because consumers don't want to pay. Thus companies produce crap to meet that demand, and that gives China a bad name.
What is boils down to is the specification and the quality assurance process. If a product meets the right spec, it doesn't matter where it is made.
I hate to tell you this, but some things made in America are crap too.
