Low Alloy Steel Wire

COREFIL-Ni (MOD)

AWS: SFA 5.29 E81T1-G

EN ISO CODE:

Corefil-Ni (Mod) is a low alloy and hydrogen controlled (4ml max) flux cored wire designed for welding of medium tensile steels structures subjected to dynamic loading and impact resistance requirements down to -51°C. The wire gives good performance under CO2 shielding with radiographic quality weld deposits. The wire produces thin & friable slag covering with shiny bead appearance.

Corefil-Ni (Mod) is designed for single and multi pass welding of ship building grade DMR 249 grade A steels. The wire is also suitable for fabrication of heavy & rigid structure, pressure vessels etc.
