Answer is:
steel
Explanation:
Cemented carbide tools are not found to be suitable for cutting Steel
Answer is:
lowers the toughness and transverse ductility
Explanation:
sulphur is normally regarded as an impurity and has an adverse effect on impact properties when a steel is high in sulphur and low in manganese. Sulphur improves machinability but lowers transverse ductility and notched impact toughness and has little effects on the longitudinal mechanical properties
