ABSTRACT: During the past two decades, considerable efforts have been made in the development of high
performance spring steels to meet the needs for weight and savings in the automotive industry.
During the service the suspension system will be subjected to different environmental conditions,
at the same time it has to sustain a variety of loads acting on it. Among all the wear of spring
steel plays a vital role. In this experimental analysis an attempt has been made to investigate the
performance of spring steel (EN-47 / SUP 10) under the dry sliding condition. The specimen
preparation and the experimentations have been carried out according to the ASTM G99
standards. The effects of tempering and cryogenic treatments on the performance of the spring
steel have also been determined. The results have revealed that the material condition has got a
significant influence on the performance of the spring steel. In order to analyze the percentage
contribution of different wear parameter and the material condition, the DOE and ANOVA have
been made. The results have shown that the load (49.205%) has shown the highest influence and
the material condition has shown 22.56% of contribution on wear behavior.
