ABSTRACT:
A metal push belt (1) for application in a continuous variable transmission, includes at least one endless tensile member (2), and transverse elements being provided freely moveable in the endless direction of the tensile member (2). The tensile member is produced of steel, containing non-metallic inclusions of predetermined sizes as observed in the micro-structure of a material section, in accordance with a specified diameter Dcircleof a circle relating to the surface occupation of such an inclusion observed in such micro structure, in which the steel is produced in a constitution having a nominal inclusion size distribution with diameters ranging up to 30 μm, the inclusion diameter range between 10 μm and 30 μm being less than 20% of the total number of inclusions per square unit of sliced material counted by inclusions having a size larger than 2 μm.
