DnH 25/35 Nb LC
AWS: SFA EN ISO 3581-A
EN ISO CODE:
D&H-25/35Nb LC is a low-carbon basic coated SMAW electrode for welding of low-carbon 35%Ni-25%Cr & Bal. Fe alloy steel. Weld deposit can be used at temperatures up to 1100°C & possesses resistance to thermal shock & Fatigue. Ideally suited for welding of centrifugally cast pyrolysis coils, reformer tubes, return bends, and tees for the petrochemical industry.
