EN ISO 18274 AWS A5.14 Material-No.
S Ni 6276 (NiCr15Mo16Fe6W4) ER NiCrMo-4 2.4886
Characteristics and field of use
UTP UP 776 is suitable for joining and surfacing on matching and similar alloys such as
2.4819 NiMo16Cr15W UNS N10276 and surface weldings on low-alloyed steels.
UTP UP 776 is employed primarily for welding components in plants for chemical processes
with high corrosion resistance in reducing and, above all, in oxidizing environments.
UTP UP 776 is also used for cryogenic applications such as joining 9 % Ni steels.

Welding instruction
The welding area has to be free of impurities (oil, paint, grease, markings and so on).
Welding must be performed with low heat input. The maximum interpass temperature
should be kept below 150 °C. Using dried welding flux is mandatory.
