Steel is the ferrous metal that functions as a fundamental element mixed with several parts. This research to obtain Quench Tempered Steel material with high hardness and analysis radius bending of steel treated by quench and temper methods, the influence of hold time, diameter of steel and impression rim was studied. The result shows that the high value of hardness is 498 HV with a holding time of 20 min which means steel developed has an eminence tensile strength combination, impact strength and satisfactory ductility for structural application.
