Does the landlord's question mean that austenitic stainless steel eliminates internal stress? Pay attention to say a few more words after posting and make the problem clear. If so, this is a puzzling question. Because some brands in this kind of steel are easy to cause intergranular corrosion when heated at 425 ~ 900℃ after cold working; Heating some brands in the range of 540 ~ 925℃ will lead to phase formation and reduce corrosion resistance and toughness. Slow cooling after heating increases this harmful tendency; Rapid cooling will produce new stress and increase the possibility of stress corrosion. Low heating temperature and incomplete stress relief; High heating temperature brings problems such as surface protection. What should we do among these contradictory factors? Here is a piece of information about how Americans discuss and treat this problem.
