Mechanical Properties Of Seamless Steel Tubes

It is mainly used to produce pneumatic or hydraulic components. Precision bright P9 Seamless Steel Pipe is a kind of high-precision steel pipe after being treated by fine or cold rolling. Because the inner and outer walls of the precision bright tube have no oxide layer, accept high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening without cracks, etc. Such as cylinders or cylinders, can be seamless pipes, but also welded pipes. The chemical composition of the precision bright tube is carbon C silicon Si manganese Mn sulfur S phosphorus P chromium Cr precision bright tube process introduction: high-quality carbon steel, finish rolling, non-oxidative bright heat treatment (NBK state) non-destructive testing, the inner wall of the steel pipe is brushed with special equipment After high-pressure washing, the anti-rust oil on the steel pipe is used for anti-rust treatment, and the two ends are sealed for dust-proof treatment. The main features of the precision bright tube: high precision and high smoothness of the inner and outer walls of the steel tube. The steel tube has no oxide layer after heat treatment, and the inner wall has high cleanliness. The X42 Seamless Steel Pipe receives high pressure, the cold bend does not deform, and the flaring and flattening have no cracks. Deformation and machining disposal. The color of the steel pipe is bright in white and has a high metallic luster. The main purpose of precision bright tube: automotive, mechanical parts, etc., which have high requirements on the precision and smoothness of steel pipes. Nowadays, the users of precision steel pipe are not only the users with high precision and smoothness. Because of the high precision of precision bright seamless steel pipe, the tolerance can be maintained at 2--8 wire, so many machining users save labor, materials and time. Loss, the seamless steel pipe or round steel is slowly transformed into a precision bright seamless steel pipe.
