What happens to a quench-hardened tool or machine part that was not tempered when it is subjected to shock loads or bending stress? A. It is not supposed to be tempered because once it is tempered, it will be brittle.   True False How can a steel that contains insufficient carbon to be hardened be surface hardened? A steel that contains insufficient carbon for the quench and temper process can be heat treated by diffusing carbon, nitrogen, or other hardening compounds into the surfaces of the components being hardened by methods including carburizing, carbonitriding, and nitriding. True False
