Duplex Duplex 2209

Offering a combination of high strength and high general corrosion resistance, ER2209 belongs to the family of duplex stainless steels, characterised by a microstructure consisting of roughly equal amounts of austenite and ferrite phases.

This high strength and excellent corrosion resistance make ER2209 suitable for applications in aggressive environments. Duplex 2209 combined with ARCEMY® and the WAM® process has superior resistance to stress corrosion cracking, pitting, and crevice corrosion compared to conventional austenitic stainless steels. The alloy also exhibits good toughness and ductility, making it suitable for Offshore, Marine, Oil & Gas, and Chemical Processing applications.

AML3D’s ARCEMY® and AMLSoft™ have specific processing parameters for Duplex ER2209 in WAM® applications. Appropriate process parameters, such as welding current, travel speed, and shielding gas, are carefully controlled to ensure successful manufacturing outcomes.
