GEMET 105

IDENTIFICATION : GEMET 105
MAINTENANCE ELECTRODE – CARBON STEEL

Low hydrogen electrode with good ductility & creep resistance.

ALLOY BASIS : C,Mn,Si,Mo.

CHARACTERISTICS :

Low heat in-put, All position, Basic coated electrode with high metal recovery. Easy weldability and high mechanical properties. Deposited weld metal is of radiographic quality. Weld metal is tough and resistant to ageing, high triaxil stresses and withstand heavy shocks.

TYPICAL APPLICATION :

For welding ASTM A336 Gr FJ, A335 Gr PJ.High temperature pressure pipelines, boiler tubes and boiler plates where good creep resistance is necessary.For welding of carbon steels of unknown composition. For welding creep resistance ferritic steel in steam and chemical plant,thermal power ,tube to tube,shield in heat exchange. Difficult to weld steel, highly stressed joints.
