BÖHLER NiMo 1-IG伯乐焊丝

BÖHLER NiMo 1-IG伯乐焊丝

Description
Copper coated GMAW wire for high strength, quenched and tempered fine-grained construc-
tional steels.
The wire is suited for joint welding in boiler, pressure vessel, pipeline, and crane construction
as well as in structural steel engineering. The typical composition of the wire fulfils the require-
ments of the NORSOK-regulation for „water injection systems“.
Due to the precise addition of micro alloying elements NiMo1-IG wire features excellent ductility
and crack resistance in spite of its high strength. Good cryogenic impact energy down to -60 °C,
low hydrogen contents in the deposit, best feedability and low copper contents are other
advantages of this wire.
