Hot forging of steel bars is the technique employed to produce many critical automotive components such as connecting rods and stabilizer bars. These parts typically need subsequent heat treatment to obtain the necessary properties. Microalloying adds very small amounts of certain elements to steel to improve mechanical properties, particularly strength and hardness. The new types of bar products obtainable through microalloying are outlined. These steels are both hot-rolled and cold-finished bar products. By using microalloyed (columbium or vanadium) hot-rolled bars in hot forging applications, the need for subsequent heat treatment of the as-forged parts can be eliminated in many situations. Furthermore, after cold forming or cold finishing, mechanical properties previously unobtainable using the standard grade are possible. In many situations this increased strengthening potential permits the steel user to select a lower priced bar which has the desirable properties.
