NIMONIC® 80/20


NIMONIC® 80/20

NIMONIC® 80/20 is a nickel-chromium material used for gas-tungsten-arc and gas-metal arc welding of NIMONIC® 75, and INCOLOY® alloy DS, and the Brightray® alloys to themselves and to each other. The shielding gas should be Argon, Helium, or a mixture of the two. It may also be used in many dissimilar metal applications, especially where carbon steels are joined to stainless steels and to Nickel-based alloys. Weld overlaying of carbon and low ally steels is another popular application.
