What type of steel is resistant to corrosion when using 4% hydrochloric acid (with the remainder being water), at a temperature of 20–50°C? Without considering plastics
Hastelloy C-276 can be tried
The temperature isn’t high either; why use metal materials? Non-metallic materials are cheap and easy to use
Why must steel be used? You’re challenging yourself there.
It can be lined with steel, and the regulations also classify it under metal piping management
The temperature isn’t high, so there’s no problem using it; however, given the high cost, other non-metallic materials can also be used.
