What Controls the Surface Quality of Stainless Steel Pipes?

Nov. 27, 2020

As a Seamless Steel Pipe Supplier, share with you. Do you know what determines the surface quality of stainless steel pipes? 304 stainless steel pipe, as a kind of stainless steel decorative pipe in austenite, in addition to basic mechanical properties such as good tensile resistance, corrosion resistance and high hardness, it also has a high-quality appearance, which means that the surface of 304 stainless steel pipe The brightness reaches the standard height, but it should be noted that the brightness of the 304 stainless steel tube will be reduced due to improper operation or failure to prepare during the processing.

One of the important factors affecting the surface quality of stainless steel pipes is that the oil content of the emulsion is too high. The emulsion is a necessary solution when the cold rolling mill is running and processing stainless steel plates. It is very important for the smoothness and cooling of the stainless steel plates. It works, but the emulsion contains oil, and the oil at high temperature will be cracked into carbon. If the oil in the emulsion cannot be removed in time after being carbonized at a high temperature, it will accumulate on the surface of the 304 stainless steel pipe, and indentation will be formed after rolling. Due to the high oil content in the emulsion, after annealing the inner wall of the maintenance cover, it will form carbonization and accumulate on the inner wall of the maintenance cover. In other processing processes, these carbon blacks will be brought to the surface of the 304 stainless steel pipe, thereby covering The surface of 304 stainless steel pipe affects the appearance quality. After a long period of processing operations, a lot of oil, carbon black, dust and other debris will also accumulate on the convection plate and stove. If it is not cleaned up in time, it will also fall on the surface of the stainless steel plate.

In fact, the chemical composition and surface finish of 304 stainless steel pipe have a lot to do with the manufacturing environment and cleanliness. As long as the convection plate, stove and maintenance cover are cleaned in time, the surface quality of 304 stainless steel pipe can be indirectly improved.

Keeping the surface of stainless steel pipes clean can effectively extend the service life of stainless steel pipes, save costs, and create greater use value.
