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.
