Kolsterising involves a large amount of carbon being diffused into the steel. This creates a compressive stress which causes a strong hardening of the surface, but does not effect the corrosion resistance.
Stainless steel with an austenitic structure, which has low wear resistance and hardness, is given a hardening of the surface in this process.
Steel does not only consist of iron and carbon. Other elements can influence the properties of steel.Read more
