General Characteristics
Duplex Stainless Steels combine many of the beneficial properties
of ferritic and austenitic materials to provide both high strength
and good corrosion resistance. Due to their high chrome and nitrogen
contents and duplex structure, these steels offer the following
benefits compared to 300 series austenitic grades:
• High Strength - Approximately twice the level of austenitics
• Good resistance to pitting and crevice corrosion
• Excellent resistance to stress corrosion cracking
• Good erosion and fatigue resistance
• Good weldability and increased heat transfer
• More stable pricing due to lower Ni levels than austenitic
stainless
Applications
Due to these high strength and
corrosion resistance properties, Duplex Stainless Steels are used
in a variety of applications such as:
• Pressure vessels, reactor tanks and heat exchangers
• Desalination plants and seawater systems
• Water transmission pipes
• Rotors, impellers and shafts in industrial equipment
• Digesters, storage and clarifier tanks, stock washers
and other equipment
for the pulp and paper industry
• Absorber towers, FGD systems in pollution control
• Phosphoric acid production
• Food, oil and gas, mining and architectural applications
