In an environment of 400 degrees Celsius with sulfuric acid mist, what type of steel is corrosion-resistant?

Which steel is corrosion-resistant at 400 degrees Celsius in an environment with sulfuric acid mist? Thank you!
Can 316 be used as well? The main concern is that acid mist may corrode steel at high temperatures
What industry? Use high-silicon cast iron for 400 degrees
Alumina crucibles should work fine; I’ve used them for roasting ore for 9 years in total. In muffle furnaces, crucibles are generally used – either alumina crucibles or ceramic ones. Other materials can also be used, but in practical production they aren’t employed due to cost considerations; even steel cannot withstand sulfuric acid
The crucible can be used； It seems that crucibles aren’t suitable for industrial use, as it’s not possible to make them large enough.
