Lastifil 251G deposits an alloy on cobalt base that is resistant against abrasion, corrosion and high temperatures (up to 1000 °C (1830 °F)).
The hardness obtained is independent of the cooling rate and is not changed by any heat treatment.
Rebuilding cutting blades, valve seats, guides in hot-rolling mills, extrusion blades, tar scrapers.
Hardness: 51-56 HRC.
Remove dirt, oil and all fatigued metal by grinding.
Preheat thick pieces that are prone to cracking to about 250 °C (480 °F).
Cool down slowly.
