About ER 2209

ER2209 is a duplex stainless steel filler metal (wire/rod) used for welding similar duplex grades (like 2205, 2304), offering high strength, excellent resistance to pitting and stress corrosion cracking, especially in chloride environments, and achieving a balanced austenite-ferrite microstructure in the weld. It contains about 22% Chromium, 5% Nickel, and 3% Molybdenum, making welds suitable for offshore, chemical, and petrochemical applications.

Key Characteristics:

Type: Duplex Stainless Steel Filler Metal (AWS A5.9).
Composition: High in Chromium, Nickel, and Molybdenum (e.g., ~22% Cr, ~5% Ni, ~3% Mo).
Microstructure: Deposits an austenite-ferrite mix for strength and corrosion resistance.
Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in aggressive media.
Mechanical Properties: High tensile strength.
Applications: Welding duplex stainless steels in pipelines, tanks, pressure vessels, and marine environments.

Typical Uses:

Welding UNS S31803 (Type 2205) and UNS S32304 (Type 2304) duplex stainless steels.
Joining duplex to carbon steel.
Fabrication in oil & gas, chemical processing, and marine industries
