Characteristics and field of use
UTP 80 M is suitable for joining and surfacing of nickel-copper alloys and of nickel-copperclad
steels. Particularly suited for the following materials: 2.4360 NiCu30Fe, 2.4375
NiCu30Al. UTP 80 M is also used for joining different materials, such as steel to copper and
copper alloys, steel to nickel-copper alloys. These materials are employed in high-grade
apparatus construction, primarily for the chemical and petrochemical industries. A special
application field is the fabrication of seawater evaporation plants and marine equipment.
UTP 80 M is weldable in all positions, except vertical-down. Smooth, stable arc. The slag is
easily removed, the seam surface is smooth. The weld metal withstands sea water.
