HH-814 hardfacing FCW welding wire for top surface wear resistant layer
Charateristics
It produces a wear resistant, primary carbide-containing weld deposit which is extremely resistant to abrasion, due to the finely dispersed hard niobium carbides. The weld deposit exhibit good impact resistance, offer good anti-strip performance, but cannot be flame cutting and machined. Weld deposit exhibits cracks.
Microstructure: High-chromium-high-carbon hard alloy on iron base with niobium additions: C – Cr – Nb – Fe
Machinability: Grinding only
Cutting: Not suited for flame-cutting
Cutting: Multi layers.
Application
Recommended particularly for the hardfacing of parts subjected to high abrasion and medium impact stress, e.g. Roller press top coats, Mill Roller top coats and crusher rolls. The application temperatures should not exceed 500℃.
