I wonder if the king pin or the hitch plate is heat treated? Do you have a hardness tester?I was going to make them out of 4140 and I did not think they'd need to be heat treated. No price yet.
I'm not saying that the adapters SHOULD be heat treated, only that it is something to be considered. If neither the pin or plate are heat treated then I don't see the need to do the adapters. On the other hand, if either the pin or plate are HT then I think it would be an indication that the adapters should be HT as well.
Just my
