QuNi26 Rod – Laser Welding Wire Alloy 82 / ERNiCr-3 (2.4806) – Heat-Resistant, Cryogenic to −269 °C
QuNi26 is the all-rounder among nickel-base wires: EN ISO 18274 S Ni 6082 (NiCr20Mn3Nb) · AWS A5.14 ERNiCr-3 · filler material no. 2.4806 — known as Alloy 82.
Its microstructure is austenitic and non-transformable. That is the reason for its range: it is heat-resistant with high hot strength, at the same time cryogenically tough down to −269 °C, and it suits austenite-ferrite joints — exactly where two materials with different thermal expansion meet. Also proven as a buffer layer beneath a hard build-up.
Recommended base materials
