STELLITE OR KOLSTERISING HARD FACE
STELLITE OR KOLSTERISING HARD FACE
(OP)
Anyone can explain me the difference beetwen KOLSTERISING hard face treatment and STELLITE. Which of these treatment has better wear resistance? Which has more hardness? Which is more expensive? Tanks in advance for your help.

Kolsterising is a low temperature diffusion process used to create a high resistance carbon layer (from the surface towards the centre of the material for about 20 – 40 µm). The carbon diffused in the steel lattice increases hardness and produces beneficial effects (fatigue resistance) due to induced compressive stress.

RE: STELLITE OR KOLSTERISING HARD FACE
Reading between the lines i would suggest that kolsterising increases the wear resistance beyond that of hard facing the material with Stellite, whilst also keeping the corrosion resistance of the base metal. No clue on the price though, Stellite, although not cheap i would think was cheaper because it is more widely used. Kolsterising may be expensive simply due to lack of people able to do it.
Anyone else got any experiance with this, rather than just reading from websites?

Thanks for your answer that confirm my good opinion about this hard face treatment.
RE: STELLITE OR KOLSTERISING HARD FACE
Kolsterised austenitic products also offer a good resistance to galling (adhesive wear), as despite of the increased hardness, the diffused carbon layer keeps a good degree of deformability.
The corrosion resistance of the austenitic matrix is also not affected by the treatment, and this a great achievement if compared to the effect produced by other thermal diffusing treatment, such as nitriding.
