Stainless Steel 904L
Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.
Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel
Applications:
Due to its high levels of molybdenum and nickel, Stainless Steel 904L is frequently used in high chloride environments. Examples of applications that call for the used of Stainless Steel 904L include:
♦ Wiring in electrostatic precipitators
♦ Oil refinery components
♦ Seawater cooling devices
♦ Gas scrubbing plants
♦ Pulp and paper processing industries
♦ Acetic, phosphoric and sulphuric acid processing plants
