Presicion steel pipe

The precision bright tube is a kind of high precision steel pipe material after the fine drawing or the cold rolling treatment. Because the inner and outer wall of the precision bright tube has no oxide layer, withstand high pressure leak-free, high-precision, high finish, cold bending deformation, expansion, flat-free cracks and so on a little, so mainly used to produce pneumatic or hydraulic components products, such as cylinder or oil cylinder, can be seamless pipe, there are welded tubes. The chemical composition of the precision bright tube is carbon C, Si, MN mn, sulfur s, phosphorus p, CR Cr.
