The use of stainless steel pipes is now more and more extensive. Because of its good corrosion resistance, it plays a vital role in engineering construction. In the process of production, it is necessary to perform solution treatment on stainless steel pipes. The main purpose is to obtain a certain amount of horsepower. Tensite increases the hardness of the product.
310S stainless steel pipe is a large category, which can be strictly divided into 310S stainless steel welded pipe, seamless pipe, square pipe, industrial pipe, decorative pipe and so on. Different applications are made according to different industry characteristics and product characteristics. From the perspective of domestic stainless steel pipe products, the steel grades are mainly austenitic steel; the product varieties are: seamless steel pipes include cold drawn pipes, cold rolled pipes, hot extruded pipes, centrifugally cast pipes, and spinning pipes; welded pipes include : Welded pipes such as plasma welding, argon arc welding, submerged arc welding, light speed welding and high frequency welding, the stainless steel pipes that can be produced basically cover the varieties and specifications of the standards of various countries in the world, and the specifications and varieties of stainless steel special-shaped pipes also reach more than 100 kinds. , The product uses involve many fields of industry and civil use.
In 310S stainless steel, microalloying elements form oxides, sulfides, carbides and nitrides. Niobium exhibits a strong tendency to form carbonitrides, but a relatively small tendency to form oxides, sulfides or compounds. The (Ti,Nb)(C,N) precipitates in 310S stainless steel tubes usually have the characteristics of core wrapping.
The constant temperature oxidation curve of 310S stainless steel pipe at 700, 800, 900 and 1000℃ follows the parabolic oxidation law. According to the rating standard of average oxidation rate, 310S stainless steel pipe is “completely resistant to oxidation” at the first 3 temperatures; 310S stainless steel pipe is “completely resistant to oxidation” at 1000℃. Tube “Antioxidant”.
