机译:提高铬钢的低温抗氧化性,成分和工艺

摘要

The invention relates to a heat treatment of a chromium steel (4), in particular a 9% -10% chromium steel, which is used at 673K to 823K, in which oxidation is carried out beforehand in an oven, preferably in air, at which the temperature of the preoxidation is carried out is at least 20K, in particular at least 30K higher than in the area of use, preferably greater than or equal to 873K, as a result of which a pure chromium oxide layer (20) is formed.
