SELECTARC D22/09 TIG
CEWELD® 2209 Duplex Tig is used for pipe welding and in general fabrication in the offshore oil and gas industry and in the chemical process industry. It is also suitable for cladding steels to obtain corrosion-resistant layers.
CEWELD® 2209 Duplex Tig is used for pipe welding and in general fabrication in the offshore oil and gas industry and in the chemical process industry. It is also suitable for cladding steels to obtain corrosion-resistant layers.
CEWELD® 2209 Duplex Tig exhibits corrosion resistance similar to that of grade 904L in most applications. In addition to high strength and toughness properties, CEWELD® 2209 Duplex Tig also exhibits excellent resistance to stress corrosion cracking and pitting (PREN > 35). The operating temperature range is from –40 °C to +250 °C. Ferrite content 30-60 FN (WRC)
