Stress relief of 304 stainless steel
Web2 days ago · Ferritic steels are exceptionally resistant to stress corrosion cracking, and also have good resistance to organic, nitric, phosphoric, and acetic acids. 430 can be bought as 430F stainless steel, which is a free-machining steel resistant to pitting and crevice corrosion effects. WebJul 7, 2011 · For carbon steels, stress-relief operations are typically performed at 105-165°F (40-75°C) below the lower critical temperature – in the range of 930-1200°F (500-650°C). It is also important to understand that the elimination of stress is not instantaneous, being a function of both temperature and time for maximum benefit.
