A hybrid steel cord and method of making such cord which includes, in contact with one or more carbon steel wire(s), at least one stainless steel wire whose microstructure contains less than 20% of martensite (% by volume). Articles made of plastic and/or rubber, in particular tire envelopes or the carcass reinforcement plies of such envelopes embodying such cords.

Hybrid steel cord for tires

The present invention provides a stainless steel wire for a carcass of a tire and a process for making such a wire. The wire comprises at least 0.02% and at most 0.2% carbon, at least 3% and at most 20% nickel, at least 12% and at most 28% chromium, the sum of the nickel and chromium being at least equal to 20% and at most 35% (% in weight). The structure of the steel comprises at least 20% in volume of martensite and it is devoid of austenite or it comprises less than 80% of it in volume.
