UP-100 NiCu1 (S2NiCu1)
SAW (submerged arc welding) wires for mild and low alloyed steel

Classification DIN EN ISO

14171-A S2Ni1Cu

Material No.

-

Classification AWS

A5.23 EG

Approvals

TÜV 03275, CE

Characteristics and application

Submerged arc welding wire for weathering steels. Weathering steels, with controlled additions of Cu, provide improved corrosion resistance compared to CMn steels. The improved resistance to atmospheric corrosion means these steels find use for architectural applications and also for welding CMn steels to prevent preferential corrosion of the weld.

Base materials

For weather resistant construction steels, commonly referred to as weathering steels.
