But when making steel, we all know that cold-drawn steel pipe is a kind of steel pipe with high fineness, and its use is very extensive, especially the various properties and various uses of cold-drawn steel pipe are more important manifestations of cold-drawn steel pipe. When cold-drawn seamless steel pipe is used, it is necessary to clarify the nature of cold-drawn seamless steel pipe and its application in all aspects, so as to make rational use of cold-drawn seamless steel pipe. Cold-drawn seamless steel pipe is a special case of steel pipe, but also a good steel. It can be said that the raw material of cold-drawn seamless steel pipe is also relatively special, and its utilization and market prospects are relatively large.
Cold-drawn steel pipe is a kind of high-precision steel pipe data after cold-drawn or hot-rolled treatment. Because the inner and outer walls of cold-drawn steel pipes have no oxide layer, withstand high pressure and no leakage, high precision, high gloss, cold bending deformation, flattening and no cracks, etc., they are mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes, as well as welded pipes. The chemical compositions of cold drawn steel pipe are carbon C, silicon Si, manganese and manganese, sulfur S, phosphorus P, chromium and chromium.
Common raw materials:
There are many principles for producing raw materials. As long as the steel is not too hard, it can basically be produced according to needs. For example: 10, 35, 16Mn, 40Cr.
The production process is more complicated, the production situation is better, the performance is better, and the application is constantly playing out good results, so the cold-drawn seamless steel pipe is a good steel type in a sense.
