Abstract (en)
[origin: EP1143029A1] A method for the production of a component with very high mechanical characteristics, by pressing a hot rolled steel strip coated with a protective metal or alloy, consists of cutting the strip to form a blank, pressing the blank to form the component, the production, before or after pressing, of an allied intermetallic compound at the surface acting as a lubricant and removing the surplus strip needed by the pressing operation. An Independent claim is included for the utilisation of a hot rolled steel strip coated with a protective metal or alloy in pressing operations.
