ERNiCrMo-3

UNS N06625
Werkstoff – Nr. 2.4831
AWS A5.14
ERNiCrMo-3 refers to a category of heat-resistant welding wire. It is used in construction, metallurgy, oil, medicine, heavy engineering. The weld metal has good impact strength and high resistant to embrittlement. Suitable for welding of dissimilar steels, operating at temperature of 450 - 550 °C. Is applied in an aggressive environmental exposures at high temperature and even at high humidity.
