摘要: A wire (200) comprises a steel core wire (202) and a polyamide coating layer (208) at the surface of the wire (200). The polyamide is selected from the group consisting of polyamide 6, polyamide 6.6, polyamide 11 and polyamide 12. The wire (200) comprises a polyamide-imide coating layer (206) contacting the polyamide coating layer (208) at the inner side of the polyamide coating layer (208).

摘要: An elongated steel element (12) with a martensite, tempered martensite, bainite or sorbite structure has a polymer coating (16) with a thickness lower than 20 μm immediately upon the elongated steel element (14). The friction coefficient and corrosion resistance are both improved by the polymer coating at a lower cost.
