In the industrial sector, 98% sulfuric acid is a commonly used strong acid employed in various applications, including chemical manufacturing, metallurgy, and mining. Choosing the right pump for transporting 98% sulfuric acid is crucial, but the question of whether it's safe to use 304 stainless steel pumps for handling this strong acid remains a topic of concern. This article delves into this issue to help you understand the relationship between 98% sulfuric acid and 304 stainless steel pumps.

Characteristics of 98% Sulfuric Acid: 98% sulfuric acid, also known as concentrated sulfuric acid, is a highly concentrated sulfuric acid solution. It exhibits extremely high acidity and corrosiveness, necessitating careful handling and transportation.

Characteristics of 304 Stainless Steel: 304 stainless steel is a common stainless steel material typically used in the fabrication of various equipment and components. It possesses good corrosion resistance but is not suitable for all strong acid media.

Can 304 Stainless Steel Pumps Be Used for Transporting 98% Sulfuric Acid? While 304 stainless steel offers relatively good corrosion resistance, there are significant considerations when handling 98% sulfuric acid:

1.Concentration and Temperature: 98% sulfuric acid is a highly concentrated acid typically used at elevated temperatures. Under these conditions, 304 stainless steel may corrode, making it unsuitable for prolonged transport of concentrated sulfuric acid.

2.Corrosiveness: 98% sulfuric acid exhibits a degree of corrosiveness towards stainless steel materials, especially at high temperatures and concentrations. This can lead to material degradation and a decline in pump performance.

3.Material Selection: For applications involving the transport of 98% sulfuric acid, it is more advisable to opt for special alloys such as Hastelloy C, which offer superior corrosion resistance, particularly under extreme conditions.

While 304 stainless steel performs well in some acidic media, it may not be the best choice for transporting 98% sulfuric acid, which is characterized by its high concentration and elevated temperature. To ensure the safe and reliable transport of 98% sulfuric acid, it is recommended to select materials with higher corrosion resistance, such as special alloys. Proper pump material selection will contribute to improved production efficiency, reduced maintenance costs, and a safer working environment. When choosing pump materials, it is essential to rely on professional knowledge and experience to make the best selection decision.
