LOW HYDROGEN ELECTRODE FOR WELDING HIGH TENSILE STEEL;

Product Description;

MT-48 is Iow hydrogen type electrodes containing iron powder for ordinary Iow 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/m㎡class high tensile steel of ships and bridges.

Chemical Composition of Weld Metal (%)Typical:

C(0.08) Mn(1.00) Si(0.50)

S(0.014) P(0.02)
