| Abstract: | Stainless steel butterfly valves sometimes have rust during application. We have found the key factor that makes the material get rusty through microstructure analysis, dyeing test, heat treatment and SEM test, which is the poor chrome area caused by the seperation of carbide from the material on the crystal boundry. Poor chrome area causes the rust of stainless steel butterfly valves. |
