Medium and High Tensile Steel

INDOTHERME(SPL)H4R

AWS: SFA

EN ISO CODE:

Indotherme(Spl)H4R is a basic coated, low hydrogen, moisture resistant electrode. It is suitable for mild steel and medium high tensile steels subjected to dynamic loading, high stresses and impact. Weld deposit displays excellent toughness at sub-zero temperatures down to -45°C.

Some of the applications include:
Heavy structures subjected to dynamic loading, Rail coaches, Wagons, Ships, Road rollers, Heavy duty cranes, Conveyors & other materials handling plant and equipment, Earth moving machinery, Tractors, Hydraulic gates, Rotary kiln shells, Concrete reinforcement rods, Welding cast iron, Depositing buffer layer on steels before hardfacing, etc.
