Classification:
EN ISO 18274 S Ni 6082 (NiCr20Mn3Nb)
AWS A5.14 ERNiCr-3
Description:
Cromatig 82 is intended for welding Inconel 600, Incoloy 800 and similar composition nickel base
alloys particularly where these are used for high temperature service. Highly suitable for a wide range
of dissimilar joint combinations between nickel base alloys, Monels, mild and low alloy steels and
austenitic stainless steels. Can be used to clad carbon steels with an Inconel type surface. Suitable
for welding 5% and 9% nickel steels for cryogenic applications.
