Can stainless steel and carbon steel be welded together?
Thread Content
Can stainless steel and carbon steel be welded directly to each other? Can it be achieved as long as special welding electrodes are available?
It can be welded; sub-arc welding can be used for the root pass, followed by other types of electrodes.
It can be welded, no problem. Be sure to preheat and perform post-weld heat treatment; if it’s for a less critical application, heat treatment can be skipped
I’ve learned it. I’ll come here often to exchange ideas and improve myself. Thank you
Welding electrodes 132 or 302 for welding stainless steel and No. 20 steel
I’ve learned it. Thank you:handshake
I used to only know that welding was possible, but I didn’t realize that other treatments were also needed. I’ve learned it.* Thank you!
Restoration OP: It can be welded
I’ve learned a lot of knowledge; thanks to all the experts
Welding is possible using electrodes made of different steel types, but this method is generally not recommended. If pipes made of two different materials are present, it is possible to change the material at the flange. Welding of different steel types can lead to corrosion due to the use of incompatible electrodes, which is detrimental to stainless steel pipes.
Welding is possible; it is necessary to select the appropriate welding electrode for welding dissimilar steels. The selection should be made in accordance with the \"JB/T4709-2000 Welding Procedures for Steel Pressure Vessels\"
I recommend a book: Welding of Dissimilar Steels and Metals, authored by Pan Chunxu. Published in July 2000 in Beijing by the People’s Transportation Press. Total 233 pages

Sure, but you need to choose the right welding rod. When welding carbon steel and stainless steel, ordinary welding electrodes are generally used; for welding stainless steels with higher Cr and Mo contents, electrodes such as A302 and A307 (containing 25% Cr and 13% Mo) are preferred when welding 20# steel with 0Cr18Ni9 steel. No heat treatment is generally carried out after welding.
