UTP A 1925
Gas shielded welding wire for CrNiMosteels
with high Mo-content
Application field
UTP A 1925 is used for joining and surfacing of corrosion resistant and austenitic CrNi and CrNiMo
steels of the same and of similar nature, e.g. 1.4500, 1.4505, 1.4506, 1.4538 and 1.4539. For working temperatures
of –196° C up to 400° C. Joining and surfacing on non- and low-alloyed steels are possible.
Properties of the weld metal
The weld deposit of UTP A 1925 is stainless, IK-resistant (wet corrosion up to 350°C). Good corrosion
resistance in reducing media, resp. similar steels as base metal.
