- HIGH YIELD STRENGTH STEELS
120ksi
Description
Basic coated electrode for high strength low alloy steels
Basic electrode with excellent welding characteristics, recommended for welding fine grained similar alloyed high yield strength steel (< 900 Mpa) in case high impact values are required at sub zero temperatures. These materials are used in lifting and handling machines, bridges, tanks, transports, shipbuilding, railway sector, mines, frames, crane fabrication, trailer construction, and other structural applications involving higher strength materials. Hydrogen content HD < 4 ml/100 g.
