Applications Welding of 3.5% Ni steel used for LPG tankers, LPG storage tanks and ethylene production
equipments to be used at about -100℃.
Characteristics LN-300 is an all positions extra low hydrogen type electrode for 3.5% Ni steel bo be used
at low temperature (lowest -100℃)

Good notch toughness of weld metal at low temperature is obtained because the weld
metal contains about 3.5% Ni.
Notes on usage (1) Pay attention not to exceed proper heat-input because excessive heat-input causes
deterioration of impact values of weld metal.

(2) Preheat at 50~100℃ and postheat at 600~620℃. The preheat temperature varies
in accordance with the plate thickness and the kind of steels.

(3) Dry the electrodes at 350~400℃ for about one hour before use.

(4) Adopt back step method or strike the arc on a small steel plate prepared for this particular
purpose to prevent blowholes at the arc starting.

(5) Keep the arc as short as possible.
