C45,S355J2,42CrMoS4,34CrNiMo6 Forged Steel Round Bar
Round steel is divided into three types: hot rolling, forging and cold pulling. The specification of hot-rolled round steel is 5.5-250 mm. Among them: 5.5-25mm small round steel is mostly supplied in straight bundles, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to make mechanical parts or seamless steel billets.
