filtering
Product Description
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 2205.
100 mesh 904l wire mesh Applications
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
Reasons for choosing grade 904L
316L: A lower cost alternative, but with much lower corrosion
resistance.
2205: A very similar corrosion resistance, with the 2205 having higher
mechanical strength, and at a lower cost to 904L. (2205 not
suitable for temperatures above 300°C.)
Super duplex: Higher corrosion resistance is needed, together with a higher
strength than 904L.
