Product description
– Flux-cored wire for submerged arc hardfacing
– Deposits a martensitic alloy offering good resistance to abrasion and erosion at high temperatures
– Retains good hardness up to 500°C
Product application instructions
APPLICATIONS
– For hardfacing requiring good resistance to abrasion with violent impacts, as well as for deposits requiring high hardness without major cracks.
– On solid parts, use FCW WLC as a reconstitution or undercoat and only apply the last pass with FCW W-S.
Examples Dredge pump parts, sand pumps, cylinders, bits, pulleys…

Why choose this cored wire?
- Excellent abrasion resistance WITH impact
Unlike wires that are too hard and become brittle, FCW W-S offers greater resistance to repeated impacts.
It contains chromium carbides in a tough matrix, providing shock absorption and wear resistance.
- Tenacious, slightly hardened deposit
Typical hardness: ~55-58 HRC, slightly less than FCW W-G or FCW W-O, but much more resistant to cracking.
The deposit remains stable and adheres well even under heavy mechanical stress.
- Ideal for parts subject to dynamic loads
Perfect for parts in motion, subject to load variations or hard bodies.
Avoids splintering or cracking that can occur with too-hard wires.
- Good compromise between service life and mechanical safety
Not as tough as FCW W-O or FCW W-G, but more reliable in severe conditions.
Protects without weakening the original part.
