GRIBINOX 2209

IDENTIFICATION : GRIBINOX 2209 E 2209-15

CLASSIFICATION :AWS/SFA 5.4:E2209-15, DIN 8556-86 E2293LB26 EN 1600-97 E2293NLB12

CHARACTERISTICS :

A basic coated electrode which deposits a 23% Cr/ 9 % Ni / 3 % Mo / 0.15 % N austenitic-ferritic duplex stainless steel weld metal having a ferrite content of about FN45. The electrode is designed for welding similar composition duplex stainless steels which offer an excellent combination of high strength and very good resistance to chloride induced pitting and stress corrosion cracking. A heat input range of 0.5 – 2.5 KJ/mm is recommended to maintain a favourable phase balance. The electrode deposits X-ray quality welds.


TYPICAL APPLICATIONS :

  • Off-shore platform pipe work, pipelines transporting chloride bearing products or sour gas and process vessels for chlorine environments.
  • ASTM A 182 Gr. F 51
  • USN S 31803
  • DIN 1.4462
  • Chemical and petrochemical process industries.
