ASME SFA A 5.14: ERNiCrMo-14 (UNS N06686)
EN ISO 18274: Ni 6686 (NiCr21Mo16W4)
Werkstoff Nr.: ≈ 2.4606
Description and applications*
* Illustrative, not-exhaustive list
Nickel-based filler metal used for welding nickel-chromium-molybdenum alloy UNS N06686 to itself, to steel and to other nickel-base alloys. Also used for cladding steel: it provides a corrosion-resistant overlay.
Characterized by outstanding resistance to a wide range of corrosive media under oxidizing and reducing conditions due to the association of high chromium content with molybdenum and tungsten. Excellent resistance to pitting and crevice corrosion, to stress corrosion cracking in chloride environment, and to intergranular attack in oxidizing environment. The weld metal maintains strength over a large temperature range.
This grade may be used for:
• welding of similar and dissimilar joints, mainly of duplex, super-duplex and super austenitic stainless steels;
• surfacing of steels, particularly in aggressive environments;
• applications in chemical and petrochemical processing, pollution control, oil and gas extraction, oil refining, and in marine environments.
Weldable base materials*
