The Use of Hot Forged Microalloyed Steels in Automobile Components

Abstract:

 Microalloyed steels are receiving much attention as a means of energy conservation. This paper discusses the observed effects of forging conditions and post10rging cooling rates on the mechanical properties in tests using vanadium bearing medium-carbon steel used for engine components. The results of attempts to develop a low carbon, high-manganese high toughness type of micro alloyed steel in which ferrite-pearlite-bainite structure was achieved through optimum cooling rates is described.

Keywords:

hot forged micro alloyed steel, medium carbon (0.4 - 0.5%C) steels, vanadium, addition, tensile and yield strength, automobile components.
