Description:
P 4130 is a basic coated low hydrogen electrode for welding of high strength steel. The electrode is
specially developed for welding of pipes and other equipment in base material AISI 4130 e.g high
pressure mud piping for offshore work. The weld metal retain high strength even after post- weld heat
treatment.
Applications:
High preassure mud pipes.
