Abstract: A method manufacturing a steel strip, including the subsequent steps of hot rolling the strip into a hot rolled strip, cold rolling the hot rolled strip and hot dip coating the cold rolled strip with a Zn based coating by leading the strip through a bath including molten zinc and wiping the strip after the coating using a gas knife having a knife slot from which a wiping gas is projected and the steel strip is cold rolled to a final cold rolled thickness of between 0.40 mm and 1.00 mm in a multi-stand cold rolling mill, and the coated steel sheet includes a steel substrate provided with a hot dip metal coating.

Abstract: A method for producing a steel strip with an aluminium alloy coating layer in a continuous coating process. Also, a steel strip coated with an aluminium alloy coating layer that can be produced in accordance with the method, the use of such a coated steel strip and the product made by using the coated steel strip.

Abstract: A method for hot-forming a steel blank into an article including the steps of: a. heating a steel blank to a temperature T1 and holding the heated blank at T1 during a time period t1, wherein T1 is in the range of Ac1 to Ac3+200° C. and wherein t1 is at most 12 minutes, b. transferring the heated blank to a hot-forming tool during a transport time t2 during which the temperature of the heated blank decreases from temperature T1 to a temperature T2, wherein T2 is above Ar1 and wherein the transport time t2 is at most 12 seconds, c. forming the blank in the hot-forming tool into an article and quenching it in the hot-forming tool from a temperature T2 to a temperature T3 at a cooling velocity V2 of 25° C./s or more, d. isothermal holding the article at a temperature T4 for a time period t4, e. wherein temperature T3 and/or temperature T4 is between Ms and Mf and wherein t4 is more than 10 seconds and less than 10 minutes, f. cooling the article from temperature T4 to room temperature at a cooling velocity V4.

Abstract: A method for manufacturing a coated part having very high mechanical properties using hot forming techniques. The method includes: —providing an annealed steel strip or blank or pre-shaped part that was coated with a metal or metal alloy before the annealing —if a strip is provided, cutting a blank from the strip before or after the annealing —optionally forming a pre-shaped part from the blank —heating the blank or preshaped part to a temperature of 500° C. at an average heating rate of 16° C./s or more —further heating the blank or pre-shaped part to a temperature between 700 and 1000° C. —hot forming the blank or preshaped part into a hot formed part —hardening the hot formed part. A method for manufacturing a coated steel strip, blank or pre-shaped part, and a coated steel strip, blank or part and a hot formed part.

Abstract: A method for manufacturing a coated part having very high mechanical properties using hot forming techniques. The method includes the steps of 1—providing a steel strip; 2—coating the steel strip with a layer of zinc or zinc alloy; 3—heating the coated steel to a temperature between 300° C. and the Ac1 temperature of the steel; 4—cooling the coated steel; 5—cutting a blank from the strip after step 1, 2, 3 or 4; 6—heating the blank to a temperature above the Ac1 temperature of the steel; 7—hot forming the blank into a part; and 8—hardening the hot formed part. The method can also be performed without step 4. The method can also be used for the indirect hot formed method. The method also relates to a method for manufacturing a coated steel strip, and to a coated steel strip, blank or part and a hot formed part.
