The difference between hot-rolled sound tube and cold-rolled sound tube

2018-07-26 10:01:09

The stainless steel pile-based test tube is divided into hot-rolling and cold-rolling. The hot-rolling is the method of detecting the heating of the tube by the stainless steel pile foundation and passing through the red state. The cold-rolling method is a stainless steel pile foundation inspection tube. In the normal temperature condition, through the matching of different molds, the stainless steel pile base detection tube is finally processed into the required size specifications together through the way of drawing and rolling. At present, from the market point of view, the cold processing method has basically eliminated the heat processing method. This is caused by the defect of the hot-worked stainless steel pile-based test tube: the hot-worked stainless steel pile-based test tube is heated. In the case of a molding process, the mechanical properties of the formed stainless steel pile-based test tube are relatively poor, and such a tube will often fail to meet the mechanical physical properties when it is subjected to mechanical processing. The cold-worked tubes are processed at room temperature, and the metal structure is more compact, so the mechanical properties are also better. Nowadays, it is impossible to buy hot-processed stainless steel seamless tubes on the market because of the eliminated processes. !
