Product application instructions
APPLICATION
FCW 420S is used for hardfacing and reclaiming components subject to moderate corrosion and metal-metal wear. The deposited alloy also has excellent gouging and abrasion resistant properties.
Examples Extensively used as a cladding alloy on many types of steel industry rolling mill rolls such as table rolls, pinch rolls, scale breaker rolls, coiler rolls, leveller rolls and runout table rolls. Other applications include dragline rope sheaves, dragline rope drums, hydraulic plungers, certain types of valve seats, pulp rotors.

Why choose this cored wire?
- High resistance to abrasion and corrosion
This wire deposits a stainless martensite-based alloy, equivalent to 420 (12-14% Cr stainless steel), offering :
-good hardness (~50-55 HRC) after air cooling,
-good resistance to abrasion, especially by hard particles,
-protection against light to moderate corrosion.
- Hard deposit, no heat treatment required
FCW 420-S forms a martensitic structure directly after welding, eliminating the need for additional tempering or hardening. It is therefore quick to use for hardfacing.
