Is stress relief treatment required after welding 304 stainless steel? How to deal with it?
Thread Content
As the title suggests, is heat treatment required after welding 304 to 304? What about after welding 304 and 20#?
Stainless steel does not require heat treatment; only special steels do
Whether post-weld heat treatment is required can be determined by checking its welding procedure qualification; I’ve found that many people are unaware of the role of welding procedure qualification and welding procedures. Any questions regarding welding can find answers in the PQR and WPS
We all use a fitting in between; the two materials are not welded directly to each other
Oh my god, I’m talking about the welding of different types of steel! Add fittings – I just can’t figure it out
Flanges, due to different materials, result in mismatches when the intermediate pipe fittings are connected if the flange materials are not the same
I don’t understand how he manages to use fittings in such an excessive manner! ! Also, it’s a bit off-topic!
Flanges of the corresponding material should be used for pipes made of that same material, and flanges are connected to one another in this way
Are there welding processes and evaluations for 304 and Q235B?
Austenitic stainless steels generally do not require post-weld heat treatment, that is, solution treatment. . Welding austenitic stainless steel with other steels generally also does not require it. Welding is carried out using austenitic transition electrodes. . For example, the most commonly used one like A302.
In this case, we do not allow direct welding; flanges of the appropriate material are installed at each end, and then they are joined together using bolts~~~
