SS 904l Plates

Aug 29

Stainless steel is a popular material in most industries. This material is known for its strength, durability, and corrosion resistance. One type of stainless steel that stands out is the 904I grade, which is used in various applications. 904I plates are often used to resist sulfuric and phosphoric acid acids. This blog will look closer at the common applications of stainless steel 904I plates.

What are Stainless Steel 904I Plates?

Stainless Steel 904I Plates are high-alloy austenitic stainless steels with low carbon content and combine copper, nickel and molybdenum. They offer excellent corrosion resistance compared to regular stainless steel plates and great strength at elevated temperatures. They also have good formability, weldability, machinability, strength, and wear resistance properties, making them ideal for fabrication into various industrial applications such as pressure vessels and marine equipment.                            

Common Applications of Stainless Steel 904I Plates

Chemical Processing Industry

904I stainless steel plates are widely used in the chemical processing industry. The material’s resistance to high sulfuric acid, phosphoric acid, and acetic acid concentrations makes it an ideal choice for various applications. For instance, 904I plates produce fertilizers, petrochemicals, and pharmaceuticals.

Oil and Gas Industry

316L stainless steel was the go-to option in the oil and gas industry for many years. However, 904I stainless steel plates have gained popularity recently due to their superior corrosion resistance. The material is resistant to chloride and stress corrosion cracking, which are common problems in offshore platforms and pipelines.

Marine Applications

Marine environments are highly corrosive due to the presence of saltwater. Stainless steel 904I plates offer superior resistance to seawater and brine solutions. That’s why 904I plates are preferred for fittings and shafts in marine applications.

Heat Exchangers

904I stainless steel plates are also used in heat exchangers due to their excellent resistance to high temperatures and corrosion. In high-temperature environments, 904I plates can withstand creep and stress rupture while maintaining strength and toughness.

Paper and Pulp Industry

The paper and pulp industry deals with extremely corrosive environments. Stainless steel 904I plates make pulp digesters, bleaching equipment, and evaporators. The material’s resistance to sulfuric and hydrochloric acids makes it ideal for these applications.

Conclusion:

In conclusion, Stainless steel 904I plates are popular materials in various industries, from chemical processing to marine applications. The material’s superior resistance to acids and high temperatures makes it an ideal choice for harsh environments. If you are looking for a durable, long-lasting material for corrosive environments, stainless steel 904I plates are the way to go.
