The cryogenic process is a complementary process
that has been used for the development of mechanical and
physical properties for a variety of materials. It has been
accepted commercially as an effective procedure for achieving
complete martensitic transformation in alloyed steel. The aim of
this study is to investigate the effect of deep cryogenic process (-
196°C) on the wear properties of spring steels with different
alloying elements. For this purpose, conventional heat treatment
(CHT) and deep cryogenic treatment (DCT) procedures were
applied to spring steels which alloyed with different elements in
order to reveal the effectiveness of deep cryogenic treatment.
Consequently, by examining the hardness and wear resistance of
the cryogenic-treated steels, it is aimed to reveal the effect of
alloying elements on the cryogenic processing of steels.

The cryogenic process, which triggers the hardening
mechanisms, such as the transformation of the retained austenite
to martensite and the precipitation of secondary carbides, is
generally used in the development of wear properties. A number
of publications available in the literature reported that as well as
improving the wear properties, various mechanical properties
can also be improved by cryogenic processing. In this
experimental study, the effects of cryogenic treatment on the
mechanical properties of 52CrMoV4 medium carbon spring steel
were investigated. For this purpose, conventional heat treatment
(CHT) and deep (-196°C) cryogenic treatment (DCT) procedures
were applied. Hardness, tensile and impact toughness tests were
performed for determination of mechanical properties. The
cryogenic process brings about a more homogeneous and finegrained structure in the matrix, and mechanical properties can
be improved without loss of toughness. As a result, by evaluating
the performed tests, it is aimed to determine the usability of the
cryogenic process in improving the mechanical properties of
medium carbon spring steels.
