Afrox MIG/TIG 904L

Welding Consumables

MIG/TIG 904L consumables give a fully austenitic, low carbon

weld metal with molybdenum and copper, with good resistance to
corrosion in sulphuric, phosphoric and other inorganic and organic
acids. They are not normally chosen for resistance to corrosion
in concentrated nitric acid. For service in severe chloride pitting
media, overmatching nickel-based weld metal is recommended. It
is the preferred weld metal for some lower alloy austenitics such
as Creusot UHB 34L and UHB 734L for wet process phosphoric acid
service. Applications include tanks and process vessels, piping
systems, agitators, rotors, cast pumps and valves for use in the
fertiliser, phosphoric, sulphuric and acetic acid plants, and in
salt and seawater environments. It is also used in some offshore
applications, including overlays on mild and low alloy steels.
