Carbon steels containing ________ carbon are easier to hard-face.

Carbon steels containing ________ carbon are easier to hard-face. Correct Answer < 0.35%

Hard facings can be applied to most ferrous metals, but with a few exceptions. Carbon steels containing less than 0.35% carbon are relatively easy to hard-face. Welding becomes more difficult with increasing carbon content and hence must be preheated and postheated for hard-facing.
