Cast iron is very stable and better wearing than steel.

Not a metallurgist here, but I thought CI was softer than most steels,
and more subject to wear by abrasion?


It is. Not sure that 'better wearing' is meant to imply
resistance though.

Castings also are notorious for warping due to residual
stresses left when the thicker parts cooled slower than
the thinner parts. Cold-rolled plate will have residual
stresses too, but hot-rolled and annealed should minimize
them.
