Sulfuric acid concentration: 2%, temperature: 120. What materials are recommended for use?
Stainless steel, containing nickel; 316L is preferred
Thank you for your reply; 316L is not suitable
There seems to be austenite-ferrite duplex stainless steel. I remember having seen drawings of containers for sulfuric acid before; they were Japanese-imported materials that were very expensive, around 50,000 yuan per piece. .
Found it; it’s called a copper sulfate filter, and the S32750 material used is imported from Japan

Enameled equipment is cost-effective and resistant to acid corrosion.
May I ask which standard this screenshot comes from? Learn* about it. Thank you
