FCW 19 9 6 O
Cored wire for self-protected arc hardfacing
Product description
- Flux-cored wire for welding without gas shielding
- Deposits an austenitic stainless steel resistant to cracking, impact, cavitation and corrosion
- Scaling-resistant up to 850°C, highly insensitive to thermal shock
- The alloy hardens in service if subjected to impact or rolling.
Product application instructions
Applications
FCW 19 9 6 O is indicated for reconstitution and buttering prior to hardfacing. It is suitable for welding manganese steels, as well as heterogeneous assemblies including difficult-to-weld steels.
Examples
Repairs to rails, switches, railway wheels, crushers and excavators. As a general rule, hardfacing of parts subjected to severe impact, high pressure, corrosion or cavitation.

Why choose this cored wire?
FCW 19 9 6-O flux-cored wire is an excellent choice for hardfacing operations on difficult-to-weld steels, such as manganese or high-carbon steels. Here’s why we choose it:
- Excellent resistance to cracking
One of its greatest assets is its excellent tolerance to hot and cold cracking. It is formulated to offer excellent ductility, making it ideal for reloading parts sensitive to welding stresses.
- Austenitic stainless steel deposit
With a typical composition of 19Cr – 9Ni – 6Mn, the deposited metal is tough, non-magnetic and stainless, giving it :
-good corrosion resistance
-very good resistance to cracking, even after several coats
-ability to absorb shocks, particularly on parts working under compression or repeated impact
- Frequently used as a buffer layer
This wire is often used as an intermediate layer before carbide-rich hardfacing. It bridges the gap between a difficult base metal (such as hard steel or manganese) and a very hard layer, which would be more brittle if welded directly to the substrate.
- Typical application
Reloading of crusher jaws, tracks, blades, construction equipment parts
Transition layer on austenitic manganese steels
Repairs to cracked or mechanically highly stressed parts
In a nutshell
The FCW 19 9 6-O is an essential charging wire for :
-welding on “temperamental” substrates
-avoid cracks
-apply a soft base before a hard coat
It combines resilience, corrosion resistance and good weldability, even in the most technical cases.
