EXETREME ABRASION WITHOUT IMPACT
DESCRIPTION
Tubular electrode filled with W and Cr carbides. Deposits highly resistant to abrasion without impact. Composed of W carbides in austenitic matrix that contributes an excellent friction coefficient and exceptional resistance to abrasion. No slag deposit. The weld material is not machinable. The welding deposit can be increased by introducing a second electrode in the arc. Designated for pieces subjected to high mineral abrasion and temperature up to 300°C.
APPLICATION
- Surfacing of all austenitic steels , cast iron, tool steels or highly alloyed steels.
- Civil and agricultural engineering
- Mixers.
- Blades
- Conveyor screws
Technique and recommendations:
For buffer layer use Z-2911 or Z307HR. If building is necessary apply Z-151. Maintain an arc length of 2-5 mm. Weave with the electrode. Hold the electrode perpendicular to the surface. Do not apply more than 2 or 3 layers.
