This is a list of the largest steel-producing companies in the world mostly based on the list by the

World Steel Association World Steel Association, often abbreviated as worldsteel, is the international trade body for the iron and steel industry. The association is one of the largest and most dynamic industry associations in the world, with members in every major ste ...

. This list ranks steelmakers by volume of steel production in millions of tonnes and includes all steelmakers with production over 10 million in 2021. The World Steel Association compiles a list from its members every year. Note that due to mergers, year-to-year figures for some producers are not comparable. Also note that not all steel is the same; some steel is more valuable than other steel, so volume is not the same as turnover.
