Experts at the 2009 International Conference for Auto Steel and Its Applications in Dalian have arrived at a consensus about the importance of greenfield, energy-saving auto steel to its producers. Since carbon dioxide (CO2) emissions from the vehicle-dominated transportation sector account for about one quarter of the world’s total CO2 emissions, outcries for tightening controls on car emissions have been mounting. Therefore, steelmakers are increasingly required to produce materials of high quality to meet this trend. As steel comprises 70 percent of the car structures, it is imperative for the industry to focus on the production of lighter, higher strength, precision and easier-cutting steel. Attempts have been made by various producers around the world to concentrate on light metal, high-strength compound materials as an alternative to the traditional steel-frame parts.
