Kolsterising® offers the solution for austenitic stainless steels by improving mechanical wear properties without adversely affecting corrosion resistance.
Kolsterising® is a proven process extending the lifetime of products thereby imparting economical advantages as well as technical advantages.

In close collaboration with the French CETIM and the Laboratoire de Tribologie et Dynamique des Systèmes de l'Ecole Centrale de Lyon the effect of the Kolsterising® process on austenitic stainless steels was tested. The results revealed that the Kolsterising® process considerably increases wear resistance.
Also other wear tests have been carried out using the pin-on-disc method and the strip-on-plate method, with both components of the same material. The results revealed that kolsterised steel have a wear resistance comparable to that of the reference materials (e.g. martensitic AISI 431). Surface roughness values after a wear test fall into a narrow range, irrespective of the wear conditions for the kolsterised steels.
