Regarding the manufacturing of duplex stainless steel
Thread Content
I would like to ask the experts about the key points in manufacturing double-phase stainless steel equipment, with a focus on the considerations specific to heat exchanger devices. Thank you! ! !
Issues related to cold forming deformation rates, changes in the microstructure during hot working and hot forming, heat treatment problems, welding processes, weld microstructure, corrosion resistance, and so on
The material has a high strength-to-yield ratio; pay attention to controlling the deformation rate! Weld heat treatment strictly follows the process specifications to control the precipitation of sigma phase
