Chemical Surface Treatments

Case hardening stainless steel surfaces using the Kolsterising process

The Kolsterising process is marketed in the UK by Bodycote S3P Group (www.bodycote.com, S3P@bodycote.com). Kolsterising improves the wear resistance of stainless steel part surfaces, without degrading their corrosion resistance. There are no additions of chemical elements to the steel during the process.

Surface hardening of Austenitic Stainless Steels with Nitrogen

It is well known that Austenitic Stainless Steels cannot be through hardened, so whilst they remain a preferred choice of Stainless Steel for many applications they are very susceptible to wear and galling.
