7018-1

type 
Basic CTOD tested extra low hydrogen electrode for stick welding
applications 
High strenght steel constructions, offshore platforms, pipe welding, shipbuilding, vessel, rigs, drilling, repair welding etc.
Properties 

The 7018-1 is a low-hydrogen electrode suitable for highly stressed joints with very easy weldability and extreme high mechanical properties for steel and steel castings up to 610 N/mm2 tensile strength and fine-grained steels with increased yield strength. It is particularly suited for welding on AC and DC+. The 7018-1 is suitable for steel with up to 0.6% carbon and has extreme low hydrogen content. HD < 3 ml/100gr. 7018-1 full fills the US Military specifications (M designation) according AWS against moisture pick up.
