More Details

Product Description

HH-814S is a high performance hardfacing flux-cored welding wire (FCW) specially designed for surfacing the top coats of roller presses, mill rollers and crusher rolls subjected to high abrasive wear combined with medium impact stress. The deposited metal contains primary carbides and fine dispersed hard niobium carbides, which provides extremely strong resistance to abrasion and long service life in severe working conditions.

Product Features

Feature	Description
Wear Resistance	Fine dispersion of hard niobium carbides provides extremely strong resistance to high-stress abrasive wear.
Impact Resistance	Good impact resistance, suitable for medium impact stress conditions.
Anti-stripping	Good anti-strip performance.
Microstructure	High chromium high carbon iron-based hard alloy with niobium addition: C - Cr - Nb - Fe.
Machinability	Grinding only.
Cutting	Not suited for flame-cutting.
Weld Bead Appearance	The weld metal will show cracks, which are typical stress-relief cracks of hardfacing deposits.
Surfacing Method	Multi-layer surfacing.
Working Temperature	Application temperature should not exceed 500°C.
