Seeking advice on the severe deformation problem during the welding of austenitic stainless steel
Thread Content
Austenitic stainless steel suffers severe deformation during welding, and now correction is necessary. Should it be corrected by cold methods or hot methods? If hot correction is used, what kind of heat treatment is required? The medium used in the equipment is liquid ammonia
I have a question: if the medium is liquid ammonia, why isn’t Q345R material used? What is the reason behind the poster choosing this material?
Reply to 2# Hongxiu Tianlan: The medium contains methylammonium
The poster is referring to methylamine, right? First of all, the poster needs to understand what heat treatment is and what cold processing is; processing at temperatures higher than the material’s recrystallization temperature is considered heat processing. The opposite is cold working. Cold correction is generally used, as hot correction tends to damage the structural structure of the material. Also, no images are visible. I don’t know to what extent it will deform!
