TYPE

Basic core wire alloyed electrode for welding Super Duplex

APPLICATIONS

Welding wrought, forged or cast super duplex stainless steels for service in the as-welded condition. Heterogeneous welding between super duplex stainless steels and dissimilar welds between other stainless and mild or low alloyed steels.

PROPERTIES

Ceweld 4501 Kb is a basic coated electrode with a fully alloyed core, the duplex weld deposit provides exellent resistant to pitting, chloride stress corrosion cracking and intercrystalline corrosion due to the high CrMo(N) content (Pitting index >40). Furthermore, the weld metal alloy is saltwater-proof and offers high tensile strength, as a result of nitrogen being added to the alloy.
