Abstract: A roller chain and a method of making a roller chain are described. The roller chain according to the present invention includes inner plates, outer plates, and pins that are formed of a chromium-molybdenum steel alloy having the following composition in weight percent: C 0.33 to 0.38 Si 0.15 to 0.35 Mn 0.60 to 0.90 P 0.030 or less S 0.030 or less Ni 0.25 or less Cr 0.90 to 1.20 Mo 0.15 to 0.30 The balance is iron and unavoidable impurities. The alloy is subjected to a hardening heat treatment to provide the desired properties of hardness and strength. The disclosed chain and method provide a cold-resistant roller chain that is better adapted for use at very low temperatures of ?10° C. or lower than the known roller chains.
