The development trend of 316L stainless steel welded pipe
In recent years, the stainless steel welded pipe market has been a "big hot". Because of its good heat transfer performance, it is widely used as a stainless steel heat exchange tube. Looking forward to the development trend of 316L stainless steel welded pipe.
First, the carbon content of 316L stainless steel welded pipe is 0.03, which can be used in applications where annealing after welding and high corrosive requirements are not possible. 316L stainless steel welded pipe has corrosion resistance due to the addition of molybdenum. It is characterized by good pitting resistance; higher high temperature strength; excellent working hardenability (weak magnetic after processing); solid solution is non-magnetic.
Secondly, 316 and 317 stainless steel welded pipes are stainless steel containing molybdenum.
Third, the molybdenum content of 317 stainless steel welded pipe is slightly higher than that of 316 stainless steel welded pipe. Because the steel contains molybdenum, the overall performance of the steel is better than 310 and 304 stainless steel. At high temperatures, when the sulfuric acid concentration is lower than 15% and higher than 85%, 316 stainless steel has a wide range of applications.
Fourth. 316L stainless steel welded pipe has good resistance to chloride corrosion, so it is usually used in marine environments.
Fifth, the corrosion resistance is better than 304 stainless steel welded pipe, which has obvious advantages in the use process.
Sixth, do not use 316 stainless steel continuously in the range of 800-1575 degrees, but when used continuously outside this temperature range, stainless steel has good heat resistance.
Based on the above advantages, 316L stainless steel welded pipe can be seen in all walks of life. It is believed that stainless steel welded pipes will be widely used in the near future.
