PERMAMENT BRAND

LOW HYDROGEN ELECTRODE FOR WELDING

HIGH TENSILE STEEL


Description:

MT-48 is low hydrogen type electrodes containing iron power for ordinary low alloy steel. As the covering contains iron powder, it welds with high efficiency, the melting rate is around 110%. It operates in all positions on DC and AC (AC open circuit voltage 70V.) The deposited metal has high plasticity, better toughness and crack resistance.

Applications:

For welding key structures and 50 Kg/mm2 class high tensile steel of ships and bridges.
