Estimating the term…
A process for the manufacture of a part with very high mechanical properties, formed by stamping of a strip of rolled steel sheet and more particularly hot rolled and coated with a metal or metal alloy ensuring protection of the surface and the steel, whereby: the steel sheet is cut to obtain a steel sheet blank, the steel sheet blank is stamped to obtain the part, an alloyed intermetallic compound is applied to the surface, before or after the stamping, ensuring protection against corrosion, against steel decarburization, which intermetallic compound may provide a lubrication function, the excess material from the steel sheet required for the stamping operation is trimmed.
