Q: What is grade 904L stainless steel?
A: Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. It contains high amounts of chromium, nickel, and molybdenum, which contribute to its exceptional corrosion resistance properties. The addition of copper enhances its resistance to sulfuric acid and other aggressive environments.
Q: What is 904L stainless steel used for?
A: 904L stainless steel is widely used in various industries due to its excellent corrosion resistance. It is commonly used in applications involving strong acids, such as sulfuric acid, phosphoric acid, and acetic acid. It finds applications in chemical processing plants, pharmaceutical industries, petrochemical plants, seawater and brackish water handling equipment, and offshore oil and gas production.
Q: Is 904L steel better than 316?
A: Yes, 904L stainless steel is generally considered superior to 316 stainless steel in terms of corrosion resistance. While 316 stainless steel offers good corrosion resistance, 904L provides even higher resistance to a wide range of corrosive environments, including acids and chloride-rich environments. Additionally, 904L stainless steel exhibits better resistance to pitting and crevice corrosion compared to 316.
Q: What is the ASTM standard for 904L?
A: The ASTM standard for 904L stainless steel is ASTM A240/A240M. This standard specifies the requirements for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. ASTM A240/A240M outlines the chemical composition, mechanical properties, and other relevant specifications for 904L stainless steel.
