 Our Products

Honing tube and rolling tube inside and outside wall oxide layer, to withstand high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening without cracks a bit, so mainly used to produce pneumatic or hydraulic components products, such as cylinder or cylinders, which can be seamless. Chemical composition of two kinds of materials are C, Si, Mn , S, P, Cr. Relatively speaking rolling tube better than honing tube good.
