Wear-resistant welding consumables

Hardfacing products matched to stated wear conditions.

KHANDU uses the customer's stated abrasion, impact, temperature, base material, welding process, target deposit and repair conditions when matching hardfacing electrodes and wires.

Product overview

Understanding Hardfacing consumables

Hardfacing is a wear-control strategy rather than one consumable classification. The deposit must be selected around the dominant wear mechanism, base material and repair method; maximum hardness alone is not a reliable indicator of service life.

Classification framework: Application-defined; AWS and EN ISO classifications vary by alloy and process
Welding process: SMAW, FCAW, GMAW, SAW, GTAW, PTA or other overlay processes
Product form: Electrodes, wires, rods, strips or powders

Typical application context

Components exposed to abrasion, impact, metal-to-metal wear, erosion, heat or combined mechanisms.
Build-up and dimensional restoration, often followed by a wear-resistant final layer.
Mining, cement, steel, earthmoving, agricultural and general maintenance components.

Key selection considerations

Actual wear mechanism, abrasive size, impact level, temperature, corrosion and operating load.
Base-metal weldability, crack tolerance, buffer layer, dilution, layer count and machining needs.
Available process, deposition rate, welding position, repair geometry and field constraints.

Application details

Component, base material and current failure or wear mode.
Abrasion, impact, metal-to-metal wear, corrosion and temperature.
SMAW, FCAW, GMAW or other available process.
Target hardness, number of layers, machinability and crack tolerance.

Testing matters

Hardness alone does not define performance. KHANDU uses application details, manufacturer capability and customer field feedback to narrow the suitable product route.
