Mechanical properties of precision bright seamless tubes | Uses and calculation methods

Precision bright seamless Steel Pipe is a kind of high-precision steel pipe material processed by fine drawing or cold rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision bright tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or The oil cylinder can be a seamless pipe or a welded pipe. The chemical composition of the precision bright tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. Brief introduction of precision bright tube process: high-quality carbon steel, finish rolling, non-oxidative bright heat treatment (NBK state), non-destructive testing, the inner wall of the Steel Tube is brushed with special equipment and washed with high pressure, the anti-rust oil on the steel tube is used for anti-rust treatment, and both ends are sealed For dustproof treatment.
The main features of the precision bright tube: the inner and outer walls of the steel tube have high precision and high smoothness, the steel tube has no oxide layer after heat treatment, the inner wall is clean, the steel tube is subjected to high pressure, the cold bending does not deform, the flaring and flattening have no cracks, and various complex deformations can be made. and mechanical processing. Steel pipe color: bright white with high metallic luster.
The main purpose of precision bright tube: automobiles, machinery parts and other machinery that have high requirements on the precision and smoothness of steel tubes. And the current users of precision steel pipes are not only users who have higher requirements for precision and finish, because precision bright seamless steel pipes have high precision and can maintain tolerances within 2--8 wires, so many machining users save labor, materials, The loss of time will gradually transform the seamless steel pipe or round steel into a precision bright seamless steel pipe.
