Hyundai S-8018.W is an iron powder low hydrogen type electrode for all position welding. It shows high resistibility to the atmospheric corrosion, since its weld metal contains Cu an Ni.
Crack resistibility and mechanical properties are good
Typical Applications:
Welding of weathering steels
CORTEN and their equivalents
High resistance to corrosion caused by seawater or combination of oil, gas and seawater.
Suitable for off- and on-shore construction
Keep the arc as short as possible, and avoid large width weaving.
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.
