The forecast comes as the industry is roiled by a collapse in prices, the fear of cheap Chinese steel flooding markets, and the social impact of cutbacks to production.
"The economic environment facing the steel industry continues to be challenging with China's slowdown impacting globally..." said T V Narendran, who heads the economics committee of the World Steel Association, or worldsteel.
After dropping by 3 per cent last year, global steel demand will decrease by another 0.8 per cent this year to 1,488 million tonnes, worldsteel predicts.
Chinese demand for steel is expected to decline by 4.0 per cent this year followed a 3.0 per cent drop in 2017 to 626.1 million tonnes.
