✦ Synopsis

Most regular users o f 304 a n d 316 austentttc stainless steel are a w a r e of its limitations, in particular, limited w e a r resistance a n d the risk o f galling. They are also aware of the disadvantages o f the processes f o r stainless steel hardening, such as the introduction of foreign elements into the surface, changes in shape, size a n d colour, separation and peeling of the surface layer a n d substantial corrosion resistance. Now, c o u r t e s y of Hardiff BV, there is Kolsterization *), the result of some revolutionary thinking and years of research. Kolsterization offers n e w design possibilities and extends the application limits for austenitic stainless steels and nickel alloys. Hardiff has applied its product
