Ed, if you meant the one with all the holes that fits in the ends of the lift arms, they are usually good material (1045) or better, but are in an unhardened state. Ones for larger tractors are usually a little harder.
When welding the stubs on when making a new one or repairing an old one I usually flame cut a 1 inch or deeper slot in the end and then insert the stub in this slot and weld it in using 7018 rod.
