ELECTRODES HIGH TENSILE STEEL ELECTRODES PREMIER - 7018-1

HIGH TENSILE STEEL ELECTRODES - PREMIER - 7018-1

CHARACTERISTICS :

PREMIER 7018-1 is a heavy coated, all position, low hydrogen type electrode which gives extremely smooth arc, medium penetration, least spatter with an easily removable slag. Deposition efficiency is about 115%. Electrode is specially designed for high impact  values at sub-zero temperatures. It can also be used on mild steel applications where the structures have to withstand sub-zero temperatures. It is recommended to use minimum possible heat input while welding.

APPLICATIONS :

Structural steels, Low alloy steels, Low temperature steels, High carbon steels, Rails, Wagons, Bridges, Boilers, Pressure vessels, Tanks, Ship-building, Cranes, Machine building,  for joining seals, speed rings and spiral casings of turbines, joining alloy steels such as Si-Mn, heat treated steels containing Ni. upto 1.0%. For heavy joints under  restraint and subject to dynamic loading.
