Mr Mittal said he believed the steel market in North America would grow by between 6% and 7% and demand in the rest of the world to rise by 4% to 5%.
His forecasts are more bearish for Europe and bullish for North America than the World Steel Association.
The association forecast last month said that steel use would increase by 3.6% following growth in 2011 of 5.6%. It also said it expected world steel demand would grow by 4.5% in 2013. Its forecast for Europe is for steel use to slip by 1.2% this year, with a modest recovery of 3.3% in 2013. This projection would leave EU steel demand to only 79 percent of the pre-crisis 2007 level. For NAFTA it sees growth of 5.2% and 5.1% in 2012 and 2013 respectively, with U.S. demand reaching 92 percent of the 2007 level in 2013.
