FCW Ni520
Nickel-based super-alloy flux-cored wire
Description & applications
• Nickel-based super-alloy flux-cored wire
• Weld metal is a precipitation hardened alloy designed to withstand impact, compression, oxidation, corrosion and heat up to 950°C
• Excellent thermal shock resistance
• Can be machined without previous heat treatment
APPLICATIONS
FCW Ni 520 is designed in general to surface all parts undergoing mechanical stress combined with corrosion, thermal shocks and/or high temperatures
Examples
High-speed forging hammers, hot drawing dies, etc.
