Pre honed seamless steel tube, also called ready to honed or ready to skived seamless steel tube, is used for production of hydraulic cylinder. The common materials for pre hone tube are ST45, ST52, 1026, E255 and E355. One main advantage of the pre honed seamless tube is the high precision dimension as compared to hot finished tubes. The tolerance is of tight control helps clients to save material waste and improve production efficiency.
Dingxin Steel Tube Manufacturing Co., Ltd, as a professional pre honed tube manufacturer, has been manufacturing and exporting pre honed tubes for around 20 years.
