Press methods for coated steels and uses of steels

A method for hot forming a structural component system in a multi-step apparatus, said multi-step apparatus comprising:

• a lower body,
• a mobile upper body,
• a mechanism configured to provide upwards and downwards press progression of the mobile upper body with respect to the lower body,
• a press tool configured to draw a blank;
• and
• a cooling tool upstream from the press tool,
• wherein the press tool comprises:
• upper and lower mating pressing dies, each pressing die comprising one or more working surfaces that in use face the blank, and
• the upper pressing die is connected to the upper body and the lower pressing die is connected to the lower body, wherein:
• the cooling tool comprises upper and lower cooling dies comprising one or more working surfaces that in use face the blank, and
• the lower cooling die is connected to the lower body and the upper cooling die is connected to the upper body,
• the method comprising:
• providing a blank made of an Ultra High Strength Steel (UHSS) coated with an aluminium-silicon coating;
• heating the blank to above an austenization temperature, wherein the austenization temperature is an Ac3 temperature;
• cooling the complete heated blank in the cooling tool, wherein cooling the complete heated blank comprises cooling down the blank at a rate above 50° C./s and below 200° C./s such that the cooled down blank leaves the cooling tool at a temperature between 600° C. and 800° C.;
• and
• drawing the blank in the press tool and transferring the blank between the cooling tool and the press tool, wherein a temperature of the blank in the press tool before drawing is in a range between 550° C. and 650° C.
