304 is generally sufficient, but it also depends on temperature and pressure; each case needs to be analyzed on its own.

The temperature is -5 degrees. . . . . . . . .

The temperature is -5 degrees; under such conditions, using carbon steel is also an option! ! ! ! ! ! ! ! ! !

I’ve seen an ethylene glycol regeneration skid where the inlet tank section is made of carbon steel.

Is ethylene glycol corrosive? Is it hot? I don’t think there’s any problem with carbon steel

The factory uses carbon steel, -20℃
