摘要

The invention relates to a method for producing a metal oxide protective layer (24) on a stainless steel (26), the metal oxide protective layer (24) being produced by annealing the stainless steel (26) in an oxygen-containing atmosphere, the metal oxide protective layer (24) at an oxygen partial pressure of the oxygen-containing atmosphere between 0.00001 bar and 2 bar. The invention further relates to a low-temperature component (20) of a fuel injection or a fuel cell, the low-temperature component (20) at least partially consisting of a stainless steel (26), the stainless steel (26) having a metal oxide protective layer (24) applied in terms of process technology, wherein the metal oxide protective layer (24) has a chromium oxide and / or a metal mixed oxide containing at least chromium.
