DIM-L-1.4462-Duplex
Welding wire DIM L-1.4462
Description:
Material no.: 1.4462
DIN 8556: SG X 2 CrNiMoN 22-5-3
EN ISO 14343-A: G 22 9 3 N L
EN ISO 14343-B: SS2209
UNS: S 31803 / AFNOR: (Z 5 CNDU 21.08)
AWS A5.9: ER2209
Highly alloyed, highly corrosion-resistant
Characteristics:
Solid-wire electrode, is ideally suited for the welding of ferritic-austenitic duplex steels. In addition to high strength and toughness properties, the weld metal has excellent resistance to stress corrosion cracking and pitting (PREN> 35) in chloride-containing media. Excellent resistance to hydroabrasive wear and good cavitation resistance. The welding additive can be used in the temperature range from -40° C to +250° C. In order to achieve the special properties of the weld, a controlled mixing and appropriate root protection must be ensured. Ferrite content 30-60 FN (WRC). The solid wire electrode is characterized by excellent sliding and conveying properties and very good welding and flow behavior.
Application:
Components (primarily castings) for the extraction of sea and brackish water, salt solutions, sulphide-containing
wash waters in petrochemical plants, as well as flue gas desulphurization plants.
Materials:
Similar duplex steels as well as similarly alloyed, ferritic-austenitic materials with increased strength.
