OK Autrod NiCrMo-3

Bare corrosion and heat-resisting Ni-Cr-Mo rod for welding of high alloyed heat-resisting and corrosion resisting materials, 9%Ni-steels and similar steels with high notch toughness at low temperatures. The filler metal is also used for welding of dissimilar joints containing non- and low alloyed steel. The weld metal has good mechanical properties at high and low temperatures. Good resistance to pitting corrosion and stress corrosion cracking. The alloy is extensively required for weld cladding of valve components and pipe inner diameters in oil and gas applications.
