Shell-and-tube heat exchanger, material selection for heat exchange tubes

The heat exchanger is a tubular heat exchanger; the fluid in the shell side is soft water at around 140 degrees, while the fluid in the tube side is nitric acid exhaust gas at around 320 degrees. What material should be used for the heat exchange tubes?

When choosing from stainless steel materials, which one is more suitable for these operating conditions: 304L or 321? 2205 offers resistance to chlorine and sulfides, while nitric acid exhaust contains nitrogen oxides

Titanium tubes can react with nitric acid under certain conditions, which is not safe, especially at high temperatures
