Can stainless steel storage tanks be used to store concentrated sulfuric acid?
Thread Content
The company has an idle stainless steel tank that it plans to use as a sulfuric acid storage tank. Sulfuric acid concentration: 92.5%
For ordinary stainless steel, it can hold more than 90% concentrated sulfuric acid at room temperature, but care must be taken regarding sealing and temperature – the container must be properly sealed and the temperature should not exceed 50–60 degrees Celsius.
What is the grade of stainless steel? Not all stainless steels can resist sulfuric acid.
18-8 stainless steel can be used to contain concentrated sulfuric acid at room temperature (around 40°C) with a relatively low corrosion rate, allowing for safe use. It is best to check the thickness of the tank every year to keep an accurate understanding.
Thank you! The material is 304.
92.5% isn’t considered concentrated sulfuric acid anymore, is it? Over 98% nicotinic acid would be sufficient, right? I think if it’s 304, it shouldn’t be able to withstand 92.5% sulfuric acid, right?
It is best to use material of grade L 316 or higher. . . 304 is not resistant to dilute acids. .
