Cause analysis on Corrosion of 2507 duplex stainless steel potash evaporation ……
Taking the actual use of evaporation tank in two projects designed by a certain institute as the starting point, the causes of corrosion cracking of 2507 duplex stainless steel equipment were analyzed from the use environment and manufacturing process of 2507 duplex stainless steel equipment, and then how to avoid corrosion of duplex stainless steel equipment in the process of design, manufacture and use was discussed. The results show that the service environment and manufacturing process of duplex stainless steel evaporation tank have great influence on its corrosion resistance, especially when there are welding defects and stress concentration caused by […]
