Description of 904L
904L is a non-stabilised low carbon high alloy austenitic stainless
steel. The addition of copper to this grade gives it greatly
improved resistance to strong reducing acids, particularly
sulphuric acid. It is also highly resistant to chloride attack -
both pitting / crevice corrosion and stress corrosion cracking.
This grade is non-magnetic in all conditions and has excellent
weldability and formability. The austenitic structure also gives
this grade excellent toughness, even down to cryogenic
temperatures.
904L does have very substantial contents of the high cost
ingredients nickel and molybdenum. Many of the applications in
which this grade has previously performed well can now be fulfilled
at lower cost by
duplex stainless steel 2205 (S31803 or S32205), so it is used less
commonly than in the past.
Applications
• Processing plant for sulphuric, phosphoric and acetic acids
• Pulp and paper processing
• Components in gas scrubbing plants
• Seawater cooling equipment
• Oil refinery components
• Wires in electrostatic precipitators
