Abstract

See full text

Disclosed are a non-normalized steel composition which includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), vanadium (V), titanium (Ti), nitrogen (N), and iron (Fe), and a method of manufacturing the connecting rod for improving yield strength, fatigue strength, and the like of the connecting rod. The non-normalized steel composition includes carbon (C) in an amount of about 0.30 to 0.55 weight %, silicon (Si) in an amount of about 0.80 to 1.20 weight %, manganese (Mn) in an amount of about 0.80 to 1.20 weight %, sulfur (S) in an amount of about 0.06 to 0.10 weight %, vanadium (V) in an amount of about 0.20 to 0.35 weight %, titanium (Ti) in an amount of about 0.01 to 0.20 weight %, nitrogen (N) in an amount of about 0.005 to 0.02 weight %, and the remainder of iron (Fe), and inevitable impurities, based on a total weight of the composition.
