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
Value Added Processing
The value added plate processing capabilities that have
serviced thousands of our satisfied customers for over
50 years are also available for your plate product requirements
in duplex stainless steels. With over 100 pieces of
plate processing equipment in-house, Sandmeyer can provide
you with nearly any shape or configuration required,
from parts that are plasma cut to abrasive waterjet
cut to "Machincut" (our Specialty
