Flux cored wire for hardfacing with hardness HRC55

Flux cored wires for hardfacing HRC 55

Name of welding wire: KB8523 Flux cored wires for hardfacing HRC55

Classification:

DIN 8555;

GB/T XXXXXXXXX; QB/KB8523-2012;

Description and application of welding wire:

Flux cored wire type KB8253 is basic medium alloyed flux-cored wire recommended for high wear resistant surfacing. The deposit is tough, free of cracks and porosity and therefore is highly resistant to deformation and impact.

On base material with low weldability is recommended depositing a buffer layer with Flux cored wire type 8253. It is suitable for rebuilding the buffer layer.

The preheat and inter pass temperature must be at least 200.

Weld deposit can be machined only by grinding.
Suitable for surfacing parts of: mixer blades and vessels, grab and bucket teeths, crusher hammers and jaws etc.

Hardness: 50 - 55 HRC

The hardness of the deposit depending on the relevant welding conditions and the chemical composition of the base metal.
