Abstract

A process for descaling a metal body, comprising the steps consisting of: immersing said body in a bath of a molten oxidizing salt; maintaining said bath at a temperature above its melting point during said immersion; removing said body from said bath after conditioning the scale of said body for its subsequent elimination.
