Alloyed Carbon Steels
These are steels alloyed to Cr, Ni, Mo and Mn that can be manufactured in their normal state, as well as quenched, cemented, annealed and tempered. They have good ductility, weldability and machinability and, when thermally treated, the alloyed steels can achieve high resistance to wear. They are mainly used by Mechanical Construction, Earth Moving, Rock Crushing & Grinding industries.
