RECTIFICADOS
Trafital offers ground round bars. The available sizes range from 3 mm to 160 mm.The round bars are supplied in either the natural or quenched and tempered condition, but it is also possible to supply ground round bars with other specific heat treatments. The standard commercial lengths are 3 or 6 meters, and upon request, fixed lengths can be supplied. The ground round bars can be supplied with a tolerance up to Class 6, and on request, custom tolerances can also be provided. The commonly available carbon steels are C45, 39NiCrMo3, and 42CrMo4. Upon request, ground bars can be supplied in other grades such as S235JR, S355J2, 18NiCrMo5, 16CrNi4, 16MnCr5, 20MnCr5, etc.
