The Right Choice Of Stainless Steel Precision Tube
Jan 14, 2019

Stainless steel precision tubes are generally used in precision instruments or medical devices. They are not only expensive, but are also commonly used in critical equipment and instruments. Therefore, the precision and surface finish requirements of precision stainless steel tubes are very high.

Common civilian stainless steel tubes are 301 stainless steel, 304 stainless steel, 316 stainless steel, 316L stainless steel, and 310S stainless steel.

One of the important factors in the surface quality of stainless steel tubes is that the oil content of the emulsion is too high. The emulsion is an essential solution for the processing of stainless steel sheets in cold rolling mills, which plays an important role in the smoothness and cooling of stainless steel sheets. However, the emulsion contains oil components, and the oil at high temperatures is cracked into carbon. If the oil in the emulsion is not removed in time after passing through high temperature to carbon, it will accumulate on the surface of the 304 stainless steel tube and form an indentation after rolling. Since the oil content in the emulsion is large, after the inner wall of the maintenance cover is annealed, carbonization is deposited on the inner wall of the maintenance cover. In other processes, the carbon black is brought to the surface of the 304 stainless steel tube to cover the surface. The surface of the 304 stainless steel tube affects the appearance quality. After a long time of processing, the stainless steel capillary tube will also accumulate a lot of oil, carbon black and dust on the convection plate and the furnace table. If it is not cleaned in time, it will also fall on the surface of the stainless steel plate.
