GRINOX 2209

IDENTIFICATION : GRINOX 2209 E 2209-16

CLASSIFICATION : AWS/SFA 5.4:E2209-16, DIN 8556-86 E2293LR26 EN 1600-97 E2293NLR12

CHARACTERISTICS :

Rutile coated electrode with authentic and ferritic microstructure. The weld metal is resistance to chloride contents media like sea water against petting corrosion as well as crevice and stress corrosion. While welding it is necessary to control heat input which should not be too less too high. Deposited weld are of Radiographic quality.

TYPICAL APPLICATION :

  • 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.

MICROSTRUCTURE :

As welded condition contain about 30-50 FN (depends upon dilution, heat input etc.)


PITTING RESISTANCE EQUIVALENT : PRE more than 34.

ASME IX QUALIFICATION : QW-432 F-NUMBER 5, QW-442 A-NUMBER 8

REDRYING : 300°C/2 hrs, max 5 cycles, 10 hr. total
