Stainless Chain identification marks

[Truce]

Hi,

My friend has 100m of stainless 10mm anchor chain. He his thinking of replacing it with Galvanised chain as he is unsure of the provenance of the chain.

The chain links are marked as shown in the attached photo. I have done a google search but come up blank so far. Is there anyone out there who knows what the marking means, where it was manufactured, grade etc?

Cheers,
Ray

I'm intrigued myself. Like you, I have googled searched high and low, but come up empty.
Might be a "Chinese" brand...it does seem to have an odd patina for stainless steel.

Hope someone can shed some light on this for you.

Why replace it, especially with galvanized? In the Caribbean we replace galvanized every four years even including end for ending. The zinc disappears. Corrosion lengthens the pitch so the chain doesn’t run on the wildcat. Rust makes a mess on the deck. Stainless is less strong but you probably don’t want to be on board when conditions test its strength. If that level of conflagration is predicted then relocate out of the path or tie up in a very secure marina. We prefer sailing south of the hurricane path. NOAA has very good storm tracking giving four days or more to sail to safe harbor.

In eight years living aboard in the eastern Caribbean we have never heard of any cruisers breaking loose of any chain due to breakage of SS or galvanized.

This particular chain could be proof tested. The usual rating for chain is 1/4 of breaking strength. That is, 4:1 safety factor.
