Automotive parts produced by cold or hot forging steel bars are often heat treated after forging to reduce their grain size and obtain improvements in mechanical properties such as tensile, impact and fatigue properties. If heat treatments after forging can be eliminated, savings in energy and handling costs could be realised.Although rolling and cold drawing without additional heat treatments have been already used, hot forged components have not except a few applications because of low toughness properties when heat treating after forging is omitted. Tests in our laboratory have shown that the toughness and other mechanical properties of hot forged parts can be significantly improved without the use of post heat treatments. Results were as follows: By using the compositional and forging controls, automotive parts that were hot forged and air cooled had properties equivalent to those of the previous parts that were hot forged and subsequently heat treated.
