Inquiry about Alloy 20 material
Thread Content
Question: Alloy 20 is equivalent to the Chinese material 0Cr20Ni35Mo3Cu4Nb. What are the corresponding standards for plates, forgings, steel pipes, and welding materials of this material? (What welding materials should be used for welding between these materials themselves, as well as when welding them with Q345R material?)
Domestically produced high-grade nickel alloys are not available; they must be imported from abroad or custom-made by large steel manufacturers such as Baosteel (ASME grades)；
