GFC 81A1

SPECIFICATION : AWS/SFA 5.29: E81T1-A1, ASME – IIC/SFA-5.29-E 81T1-A1

CHARACTERISTICS :

Tubular rutile flux-cored wire for single or multipass welding of 0.50 Mo heat resistant steels used for steam pipes of boilers of thermal power plant and similar types of steels, with CO2 shielding gas. The good weldability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag. Deposited welds arc of radiographic quality.

TYPICAL APPLICATION :

  • ASTM A 336 F1, A 204 A,B,C
  • DIN 15Mo3 (1.5415)
  • ASTM A 217 WC1, A 352 LC1
  • BS 3059 Grade 243
  • ASTM A 335 Grade P 1
  • C-Mn steel where higher tensile strength is required.
  • Chemical process plant.
