428 vs428H is there a difference.?

Question

is 428 chain the same as 428H?

Answer 1

There is a difference.

The 428H chain is designed to be a high tensile strength alternative to the 428 chain (although it is not hugely different).

For instance, whare a 428 chain may have a tensile strength of 4500 lbs, the 428H version would be about 5500.
