I have a question: the equipment’s cylinder is made of duplex steel 2205, while the jacket is made of carbon steel. Are there any issues with welding? What welding materials should be used? Also, could corrosion be a problem with this design? Thank you!

E309MoL can be used as the welding rod. Since the cylinder is made of 2205, using carbon steel for the jacket won’t save much money; it’s better to use 304 instead
