Characteristics and field of use
UTP A 776 is suitable for joint welding of matching base materials, as
2.4819 NiMo16Cr15W UNS N10276
and surface weldings on low-alloyed steels.
UTP A 776 is employed primarily for welding components in plants for chemical processes
with highly corrosive media, but also for surfacing press tools, punches, etc. which operate
at high temperature.
Excellent resistance against sulphuric acids at high chloride concentrations.

Welding instruction
To avoid intermetallic precipitations, the rod should be welded with lowest possible heat
input and interpass temperature.
