There is an existing process that involves sulfuric acid and operates at high temperatures; what material should be chosen for this purpose?
Thread Content
The current 316L is experiencing corrosion; how is it with 904?
Sulfuric acid concentration: 15%, temperature: 100°C, complete mixing
It’s usually enamel, or maybe Hastelloy (which is extremely expensive)
Low-pressure fiberglass, high-pressure 316 titanium?
Metal materials are generally subject to corrosion, but enamel can prevent this problem.
Increasing the corrosion allowance is also an option, and it is cost-effective
It’s only 100 degrees – why not use glass-lined material?
Enameled materials are relatively economical and practical; high-temperature resistant fiberglass versions seem to exist as well, so it’s best to consult the manufacturers for details.
