Steel cold including cold-rolled, cold-drawn, cold relieve tension, and spinning. Because of the low productivity of spinning, high-cost, so is mainly used for the production of diameter and wall thickness ratio of more than 2000 special thin precision tubing. Cold-rolled and cold drawn are now the main means of processing stainless steel tube production. Cold rolled advantage is that it can be well controlled to improve dimensional accuracy and surface quality properties of raw materials has been stainless steel tube. Cold-drawn cold rolling equipment than simple, low cost tools to produce great flexibility. In recent years, combined with cold rolling and cold drawing is considered the most reasonable production technology program. Quality raw materials 316L stainless steel pipe is the pipe in the most basic, so it also has a lot of hard and fast but also necessary indicators, Shandong Jinding Stainless Steel Pipe Co., Ltd. Online Service Description: hardness index on 316L stainless steel welded pipe Hop application according to the test method different ranges, 316 stainless steel U-tube, can be divided into Brinell hardness, Rockwell hardness, stainless steel U-tube manufacturer, Vickers hardness, Shore hardness, micro hardness and high temperature hardness, etc. For pipes commonly used Brinell, Rockwell, Vickers hardness of three. For harder or thin steel 316L stainless steel pipe used substandard in 316L stainless steel pipe scale, and Brinell hardness most widely Linyi stainless steel U-tube, often indentation diameter d to represent the hardness of the material, both intuitive and convenient. Providing the highest quality industrial metal pipe as the World Business Shandong Jinding Stainless Steel Pipe Co., Ltd.'s mission. The company mainly produces stainless steel pipe boilers and heat exchangers, condensers with stainless steel pipe, automobile exhaust system with a stainless steel pipe and process piping.
