性质:圆钢是最普通的型钢,分热轧、冷拉和锻制三类。热轧圆钢通常泛指包括小直径的盘条在内的圆断面钢材,直径5~250毫米。直径10毫米以上的圆钢常成条供应。几乎所有的钢种都有圆钢供应,其中铆螺钢(钢号ML2,ML3)热轧圆钢专门用于制造热顶锻或冷顶锻用的铆钉、螺钉和螺帽等,直径6~40毫米。在钢筋混凝土用钢筋中有一种光面圆钢筋(直径8~50毫米),实际上就是普通代碳钢(钢号A3,AY3)圆钢。冷拉圆钢是用热轧圆钢为原料经过冷拉加工制成的尺寸精度高的深加工钢材,直径7~80毫米,通常以直条供应。锻制圆钢是通过锻造生产的,主要供应难于热轧的合金钢钢种或不能在轧机上生产的大直径的轴坯,直径50~250毫米。
