德國UTP A 80 Ni、ERNi-1鎳基焊絲
UTP A 80 Ni nickel alloys
Classifications TIG rod
EN ISO 18274 AWS A5.14 Material-No.
S Ni 2061 (NiTi3) ER Ni-1 2.4155
Characteristics and field of use
UTP A 80 Ni is suited for joining and surfacing on commercial pure nickel grades, including
LC nickel, nickel alloys and nickel-clad steels.
Such materials are employed primarily in the construction of pressure vessels and
apparatus in the chemical industry, in the food industry and for power generation, where
good behaviour under corrosion and temperature is demanded.
The weld metal has an excellent resistance in a lot of corrosive medias, from acid to alkali
solutions.
