The solution temperature is primarily determined based on chemical composition. Generally speaking, for trademarks with a wide variety and high content of alloy elements, the solution temperature should be improved accordingly.
There are many volatile factors in stainless steel that represent the characteristics of corrosive media, namely, chemicals and their concentration, atmospheric state, temperature, and time. Therefore, if you do not understand the correct properties of the media, it is difficult to use and select materials. The following is a brief introduction to several common stainless steel materials:
Annealed seamless steel pipes with an inner diameter of more than 6.0 mm and a wall thickness of less than 13 mm can be tested using a W-B75 type Vickers hardness tester, which is very fast and simple, and is suitable for rapid non-destructive qualification testing of seamless steel pipes.
