Resumo
In order to meet the expectations of comfort from end-users, of safety and of environment regulations, a car is expected to have the following characteristics: Larger size, with air conditioning, air bag, ABS, side impact bar. Good looking. Low fuel consumption and limited atmosphere contamination. Guaranteed resistance against corrosion. Increased safety. Low cost. As a consequence, modern automotive steel products must exhibit, at high level, a combination of properties like formability, strength, fatigue, corrosion resistance and weldability, at low cost. The microalloyed steels have been meeting the desired requirements in different product forms, hot rolled strip, cold rolled sheet and forged and drawn steel grades. Hot strip products produced direct from the hot strip mill with strength levels that could only be achieved in the past with the application of heat treating. Interstitial Free steels were revamped in the early 80’s, with extremely low carbon levels. Similarly, significant changes have occurred in the long products sector. Many achievements have been possible through developments in microalloying technology. This paper presents an overview of the modern microalloyed steels – properties and alloy design – currently used in the automobile industry, covering flat and long products.
