9018-G SMAW Stick Electrodes




9018-G

 
TYPE 
Ultra low hydrogen high basic offshore elektrode
APPLICATIONS 
Crane, heavy transport, platforms, vessel and lifting equipment in offshore, pipeline, riser and applications that require NACE requirements (less than 1% Nickel).
PROPERTIES 

High basic offshore electrode according the latest offshore requirements for sub zero temperatures down to -60°C.  Suitable for steel types upto 550 N/mm2 yield strength, excellent welding properties and extreme low hydrogen content below 3 ml/100gr weld metal. The weldmetal is suitable for longer post weld heat treatments as applied in Riser applications.
