Can 304 be used at supercritical CO2 conditions of 32 MPa and 170°C? Can 316L be used?

304 stainless steel cannot be used in environments containing CO2; especially in saline conditions, particularly those with chloride ions, pitting becomes a significant problem, and this issue is even more severe at temperatures above 40–50 degrees Celsius. In a steam environment, pitting in the water accumulation area at the bottom of the equipment will be more pronounced
