What influences the quality of stainless steel tube surface

304 stainless steel tube as a stainless steel decorative tube in austenite, in addition to having good tensile resistance, corrosion resistance and high hardness and other basic mechanical properties, there is a high-quality appearance, that is, 304 Stainless Steel Tube surface brightness to a standard height, but pay attention to the processing process due to improper operation or preparation is not done, it will reduce the brightness of 304 stainless steel tube.

One of the important factors affecting the surface quality of stainless steel pipe is the high oil content of the emulsion, the emulsion is a solution necessary for processing stainless steel plate in the cold rolling mill operation, for the smoothness of the stainless steel plate and cooling play a very important role, but the emulsion contains oil components, the oil at high temperatures will crack into carbon. The oil in the emulsion after high temperature into carbon if not removed in time, it will accumulate in the 304 stainless steel tube surface, after rolling will form indentation. As the emulsion contains a lot of oil, after the annealing of the inner wall of the maintenance cover will form a carbonized accumulation in the inner wall of the maintenance cover, in other processing, these carbon black will be brought to the surface of 304 stainless steel tube part, thus covering the surface of 304 stainless steel tube affects the appearance quality. After a long time of processing operations, convection plate and hearth will also accumulate a lot of oil, carbon black and dust and other debris, if not cleaned in time, the same will also fall to the surface of the stainless steel plate.

In fact, 304 stainless steel tube chemical composition and surface finish, and manufacturing environment and cleanliness is very relevant, as long as the timely convection plate, hearth and maintenance cover inside clean, can indirectly improve the quality of 304 stainless steel tube surface.

Keeping the surface of stainless steel tube clean can effectively extend the service life of stainless steel tube, saving costs and creating greater value for use.
