According to the International Stainless Steel Forum (ISSF), the world output of crude stainless steel in the first half (January – June) of 2009 was 10.848 million tons, which had a considerable decrease of 26.7% compared with that (14.798 million tons) in the same period of 2008 and deepened an influence of the global recession arisen from September of 2008. Stainless steel products have been consumed mainly by the automobile industry. Therefore, a reduction in the manufacturing of automobiles has put a direct influence on production activities of stainless steel.
