Flux cored wire for overlay cladding welding high hardness HRC62

Flux cored ARC welding wires

High hardness Flux cored wires

Classification: DIN 8555; QB/KB4142- 2012;

Description and application:

Flux cored wire is basic medium alloy flux-cored wire recommended for highly 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 KB8253.

Note: The preheat and interpass temperature must be at least 200.

Weld deposit can be machined only by grinding.

Suitable for Rebuilding the machine parts:

Mixer blades and vessels, grab and bucket teeth, crusher hammers and jaws etc.

Hardness of overlayor welding: 60 - 65HRC;

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