Morse taper hardness

>Are Morse tapers hardened?

I ask because I bought a screw center from sears and I know it is not hardened because it has been to the nachine shop for a larger screw and we tested it before we worked on it.

I am wondering about the drive center that comes with my Jet. And other things I might order.

This is an issue because every time I use the screw center I have to beat the heck out of it to get it out again. And it is marked up where it has slipped.

Starting to worry about my bearings.
