Abstract
Process in which, during the quenching and self-tempering, a layer protecting against corrosion is formed at the surface of the bar. This layer can be produced by phosphatising with manganese, by oxidation with blowing-in an oxidising agent or by the application of a paint or of a resin. The phosphatising can be preceded by pickling. The protective layer can then be coated with a film of drying oil.
