904L Stainless Steel Material
904L is a super low-carbon high-alloy austenitic stainless steel with excellent corrosion resistance, particularly in highly acidic environments such as sulfuric and phosphoric acids. 904L contains high levels of chromium, nickel, molybdenum, and copper, which enhances its resistance to pitting, crevice corrosion, and stress corrosion cracking. It is widely used in chemical, petrochemical, marine engineering, and other highly corrosive environments.
Application Fields
- Chemical and Petrochemical Industry: Suitable for equipment and piping systems handling strong acids such as sulfuric and phosphoric acids.
- Marine Engineering: The 904L stainless steel flange is particularly suitable for seawater and salt spray environments due to its excellent seawater corrosion resistance.
- Food and Pharmaceutical Industry: Its good corrosion resistance and high purity make it ideal for piping systems in food and pharmaceutical equipment.
Advantages and Disadvantages
904L flanges offer excellent corrosion resistance, especially in highly acidic and corrosive environments, and maintain superior mechanical performance at high temperatures. The Raised Face design enhances sealing and reduces the risk of leakage. 904L stainless steel flanges are easy to weld and process, making them suitable for complex piping connections.
However, the manufacturing cost of 904L stainless steel flanges is relatively high, making them more appropriate for applications with special requirements.
