The chain is made of harder (by a substantial enough margin to not wear through too quickly) metal than the ship. Also, the cross section of any given link is much thicker than any one piece of steel in the ship so it doesn't really need to cut efficiently, it just kind of crunches and tears the ship out of the way using the ship's own weight.

They then fixed that one link and went on cutting. Keep in mind that it still is a chain and that all it took was for one link to break under a load that was not exactly typical for a chain and after some abrasion of the link itself.
