Products Description
SS 904L is a non-stabilized stainless steel grade that is known for its low carbon content. It is a high-alloy steel that contains various alloying elements, including copper, which enhances its resistance to corrosion. The presence of copper in SS 904L improves its resistivity to strong reducing acids, such as sulphuric acid.
One of the notable properties of SS 904L is its resistance to corrosion cracking, making it suitable for use in industrial applications where corrosion resistance is crucial. Additionally, SS 904L is non-magnetic, offering excellent corrosion resistance along with desirable properties such as formability, weldability, and toughness.
The combination of these properties makes SS 904L a versatile stainless steel alloy that finds application in various industries, including:
Chemical and petrochemical industry: SS 904L is commonly used in chemical and petrochemical plants due to its resistance to corrosive environments and strong acids.
Pharmaceutical industry: It is employed in the pharmaceutical industry for equipment and storage tanks that require resistance to corrosive substances and high purity.
Oil and gas industry: SS 904L is used in offshore and onshore oil and gas applications where resistance to corrosion and chloride stress corrosion cracking is essential.
Desalination plants: Due to its corrosion resistance, SS 904L is utilized in desalination plants where it comes into contact with seawater.
Food processing industry: SS 904L is employed in food processing equipment, especially in environments involving acidic or corrosive substances.
Heat exchangers and condensers: It finds application in heat exchangers and condensers due to its resistance to corrosion and high-temperature environments.
In summary, SS 904L is a non-stabilized stainless steel grade with low carbon content. It exhibits excellent corrosion resistance, especially in strong reducing acids like sulphuric acid. This non-magnetic alloy offers a combination of corrosion resistance, formability, weldability, and toughness, making it suitable for a range of applications in industries such as chemical, pharmaceutical, oil and gas, desalination, food processing, and heat exchangers.
