Stainless steel pipe is an austenitic chromium-nickel stainless steel with good oxidation and corrosion resistance. Due to the higher ratio of chromium to nickel, it has better creep strength and can continue to work at high temperatures. Has good high temperature resistance. In high temperature environment, it shows good anti-oxidation and anti-carburization performance. It can withstand smoking nitric acid at room temperature and molten nitrates up to 425°C.
