The present contribution seeks to provide an overview of the concepts of high temperature solution nitriding (HTSN) and the state of the art of the technology. It is shown how HTSN can be applied to different classes of stainless steels. New advances of HTSN are presented, in particular the combination of low temperature surface hardening, LTSH, with HTSN is addressed: HTSN is an excellent “pre-treatment” for LTSH for austenitic, duplex, ferritic and martensitic stainless steels. Examples of HTSN + LTSH of duplex and martensitic stainless steels are shown.
