FCW 420G

Tubular wire for gas shielded metal arc hardfacing

Descripción y aplicaciones

• Tubular wire for gas shielded metal arc hardfacing

• 13% chromium martensitic stainless steel deposit

• Attractive combination of corrosion, oxidation, scaling and wear resistance

APPLICATIONS

FCW 420G 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..
