Beschreibung
Zusammenfassung:	The invention discloses a steel pintle chain with low initial wear elongation. The steel pintle chain comprises at least one chain link including an open end and a closed end, wherein the open end is connected with the closed end through at least one pin. The steel pintle chain is characterized in that the closed end of the chain link is provided with a groove, and the pin closely contacts with the bottom of the inner groove of the closed end of the chain link on the same horizontal plane. By the aid of the steel pintle chain with low initial wear elongation, relative wear extent of the pin and the bent chain link is relieved, the initial wear elongation of the chain is reduced, the deformation degree of bent positions is improved, and the tensile strength of the chain link is improved by more than 15% as compared with that of an unshaped chain link.
