The design temperature is -70°C and the pressure is 8.5 Mpa. Should A320 or 30CrMo bolts be used?

Stainless steel suitable for low temperatures is better; 20592 specifies the range of applications for fasteners

Strength also needs to be considered. In 20592, both A193 and A320 are high-strength bolts.
