Consumables designed for welding of
904L alloy and gives fully austenitic weld
metal with good resistance to corrosion in
inorganic and organic acids.
Typical applications
include tanks and vessels, piping,
cast pumps, valves and other components
used in fertiliser, phosphoric, sulphuric and
acetic plants, and in salt and seawater environments.
It also used in some offshore
applications. It may be used to join Type 317L material where
improved corrosion resistance in specific media is needed.
The elements C, S, P, and Si are specified at lower maximum levels to minimize
weld metal hot cracking and fissuring (while maintaining corrosion resistance) frequently encountered in fully austenitic
weld metals.
