QuNi22 Bobbin – Laser Welding Wire Hastelloy C22 / 2.4602 (Alloy C-22 / UNS N06022)
QuNi22 is a corrosion-resistant laser welding wire of the nickel-base superalloy Hastelloy C22 (material 2.4602 / Alloy C-22, UNS N06022). This austenitic Ni-Cr-Mo alloy resists pitting and crevice corrosion in both oxidising and reducing media alike — ideal for highly corrosion-resistant build-up (cladding) welds on low-alloy steels and for joining welds of similar base materials.
Recommended base materials
- 2.4602 — Hastelloy C22 / Alloy C-22 / UNS N06022 (primary material)
- Low-alloy steels — as build-up welding / cladding
- Similar and related Ni-Cr-Mo base materials
Typical applications
- Highly corrosion-resistant build-up welding (cladding) on low-alloy steels
- Joining welds of similar and related base materials
- Chemical process industry — acetic acid, contaminated sulfuric acid and other aggressive media
- Flue-gas desulfurisation (FGD), plant and vessel construction
- Pharmaceutical and environmental engineering
Properties and advantages
- Outstanding resistance to pitting and crevice corrosion
- Resistant in oxidising and reducing media alike
- High resistance to stress corrosion cracking
- Good weldability with low heat input; shielding gas argon 4.6 or better
Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.
