A method for producing a component of a sleeve provided with an Al-Si coating steel product and intermediate product of such a method

The present invention relates to a method for manufacturing a component of a with an Al-Si-protective coating coated steel product and an intermediate product formed in the course of such a process and may be used for the manufacture of components of the type in question. During the process, the coated with the Al-Si coating steel product is subjected to a first heating step in which the temperature and duration of the heat treatment are adjusted so that the Al-Si coating is only partially pre-alloyed with Fe of the steel product, the is steel product in a second heating step is heated to a temperature above the Ac1 temperature heating temperature at which the steel product has an at least partially austenitic table structure, wherein the temperature and duration of the second heating step are set so that the Al-Si coating in the course of the second heating step is completely alloyed with Fe of the steel product, which was heated to the heating temperature steel product is converted to the component and the component obtained controllably cooled to form hard structure.
