What are the differences between materials 2520 and 825 alloys in terms of heat resistance and corrosion resistance? Which one is recommended for withstanding temperatures of up to 800 degrees?

This is a reply from a friend; I’m not sure if it’s correct. Stainless steel 2520 (310S) is suitable for high-temperature corrosion environments below 1000 degrees Celsius； 825 is suitable for a variety of corrosive media, resisting both oxidative and reductive corrosion, but the operating temperature should not exceed 550 degrees Celsius. Therefore, at 800 degrees, 2520 may be sufficient.

I agree with the netizens’ opinion; I also recommend using 25-20

I thought material 825 would be good enough, but I didn’t expect there to be a better material like 2520
