A chain link for a link chain has two legs running parallel to one another, and connected to one another at the ends via curves. The legs and curves are circular in cross-sections. The legs have smaller cross-sectional areas compared to the cross-sectional areas of the curves. The chain link is manufactured by radial forging with: providing a profile bar, and the profile bar is made of a steel material, inserting the profile bar into a radial forging machine and radial forging with reduction of the diameter of the profile bar in longitudinal portions, so that the profile bar is axially stretched in the forged longitudinal portion, wherein the diameter is reduced at least in the region of the later legs, and removing the radially forged chain link semi-finished product and forming the profile bar into a chain link as well as welding the front ends of the formed chain link.
