Low carbon steels such as 16MnCr5 and 20MnCr5 are a
widely used grade of steel in almost every industry
including aerospace, transportation, power transmission for
manufacturing of gears, camshafts, piston, pins and bearing
due to its suitable properties such as toughness, ductility,
high tensile strength, good resistance to corrosion. In this
study, different heat treatments have been applied to
improve the properties of hot forged parts. The
microstructure and mechanical properties of the hot-forged
samples have been examined in three different processes;
after normalizing was applied, cementation and tempering
applied without normalizing, and cementation, tempering
was applied on the normalized parts. As a result, when
normalization is applied before the carburization and
tempering processes an increase in core hardness and
fatigue lives were observed for the examined parts.
