FCW 25-G
Cobalt cored wire grade 25
Product description
Cobalt-based flux-cored wire
-The deposited Co-Cr-W-Ni alloy is moderately hard, but stable even at high temperatures.
Product application instructions
APPLICATIONS
-The FCW 25 is suitable for the hardfacing of parts subject to metal-on-metal wear up to operating temperatures of 800°C
-The ductility and toughness of the deposit, with very little susceptibility to cracking, mean that the FCW 25 can be used even when service shocks are severe
-Very little susceptible to creep, this grade is used for tube drilling mandrel heads, vertical rolling mill rollers, straightening guides…

Why choose this cored wire?
- Excellent wear resistance with good ductility
Unlike harder grades such as Cobalt 6 or 1, Grade 25 remains tougher, with high resistance to adhesive wear, while retaining a certain elasticity. It is ideal for parts subject to moderate impact or cyclic mechanical stress.
- Excellent high-temperature resistance
It retains its mechanical properties up to 850-900°C, making it a very stable alloy for high-temperature valves, turbines, valves and wear seats.
- Good resistance to corrosion and oxidation
Thanks to its cobalt base and chromium and nickel content, FCW 25-G is naturally resistant to hot oxidation and corrosive chemical environments, prolonging the life of recharged parts.
