High test metric chain ??
 
Is metric anchor chain available in a high test alloy such as Grade 43 chain
?

Not sure about G43 specifically, e.g from Peerless. Standard G40 is
available in metric, this is what the rest of the world uses. You may
end up using foreign-built stuff though and it could be a little more
expensive and harder to find. Maggi from Italy is excellent.

However, it is rarely "hi test" outside of the US. A related piece of
advice is: don't get confused between hi-test and high tensile. Hi-
test is just a classification and amounts to marketing fluff. In
short, it means the safe working load is a lesser ratio of the
breaking load than for non-hi-test chains (the ratio just being an
arbitrary safety margin, e.g. 4:1 is typical for anchor chain).

High tensile means steel with a strong tensile rating and hence higher
breaking strain. People typically mean G70 chain or similar. This
allows you to use lighter chain for the same strength.

Just in case it wasn't clear.

Thanks for the info.
You make a fine looking anchor.
