Abstract
In a chain with chain links of round material, the chain links have, in the region of their contact points, supporting arcs (7,8) with a supporting arc angle .alpha. of 180.degree. and a radius of curvature R.sub.s of 0.5 to 0.52 d, d being the diameter of the round material. On the side of the unwelded leg (3) of the chain link, the supporting arcs (7,8) are connected by a boundary line (9) of the clear inner space (6) of the chain link, which boundary line has an arcuate indentation (11), while the supporting arcs on the side of the welded leg (4) of the chain link are connected by a substantially straight boundary line. The greatest inner width b.sub.1max of the chain link is at most equal to 1.15 times the diameter d of the round material.
