What is the difference between HY 80 and HLES 80 steel?

HY specification is a US system, while the HLES specification is used in Europe and Asia. I'm quite sure that they both refer to the same steel (not sure if the numbers remain the same though) - a highly weldable steel often used in making hulls for ships and subs.

Thanks, that's a start in right direction for me.
