Abstract: The present invention relates to a method for manufacturing a metal strip or sheet, including the steps of providing a substrate made from stainless steel; and depositing a chromium-nitride layer on the substrate by physical vapor deposition (PVD) in a deposition installation comprising a deposition chamber and a chromium target arranged in the deposition chamber. The deposition chamber has a deposition area with a length strictly smaller than the length of the deposition chamber and at least a first prohibited area. During the deposition, the chromium nitride is deposited on the substrate only in the deposition area and no chromium nitride is deposited on the substrate in the prohibited area.
