Our duplex innovation is unmatched in the industry and our offering covers a full palette of duplex stainless steels for use in diverse industries and applications.  The duplex grades LDX 2101® and 2304 are referred to as lean duplex grades. Typical applications are storage tanks, bridges, water heaters and reinforcement bars. The corrosion resistance is comparable to the standard austenitic grades like 4301 and 4404 respectively or high alloyed ferritics like 4521. Grades 2507 and 4501 are regarded as super duplex grades. They are highly alloyed and have a corrosion resistance comparable to high performance austenitics like 254 SMO®. Typical applications for super duplex are desalination plants, seawater systems, flue-gas cleaning, umbilicals, storage tanks and pressure vessels.

Duplex grades have a ferritic-austenitic microstructure, with a phase balance of approximately 50% ferrite and 50% austenite. Duplex grades combine many of the beneficial properties of ferritic and austenitic stainless steels. The duplex microstructure contributes to the high strength and high resistance to stress corrosion cracking.

Weldability

Duplex stainless steels generally have good weldability and can be welded using most of the welding methods used for austenitic stainless steels:

  • Shielded metal arc welding (SMAW)
  • Gas tungsten arc welding TIG (GTAW)
  • Gas metal arc welding MIG (GMAW)
  • Flux-cored arc welding (FCW)
  • Plasma arc welding (PAW)
  • Submerged arc welding (SAW)
  • Laser welding
  • Resistance welding
  • High-frequence welding

Corrosion resistance

Duplex stainless steel grades are superior to standard austenitics with regard to stress corrosion cracking resistance, and duplex grades are also good in a number of acidic and alkaline environments.
