98% sulfuric acid pump type
Thread Content
To transport 98% sulfuric acid, it is required to use a magnetic pump made of 304 material. Is this feasible? Has 304 material actually been used for transporting 98% sulfuric acid in practical applications?
Sure, I have used 304 material to handle 98% acid, and there’s no problem

It can be transported directly using cast iron. 98% sulfuric acid is highly acidic and possesses strong oxidizing properties; when in contact with iron, it causes an oxidation reaction on the surface, forming a layer of oxide film that prevents further corrosion inward.
Materials such as 304 or 316 are both suitable; a passivation layer forms on the metal surface, providing protection
If you are concerned, it is recommended to use 316L and 904L
98% sulfuric acid is already considered concentrated sulfuric acid; both carbon steel and stainless steel can be used for this purpose
