The National Steel Corporation (1929 2003) was a major American steel producer. It was founded in 1929 through a merger arranged by Weirton Steel with some properties of the Great Lakes Steel Corporation and M.A. Hanna Company. Despite a difficult market in Depression-setting 1930, the company reported USD 8.4 million in profits. Again, in 1931 the company was profitable unlike many other competitors. The company could attribute its success primarily to sales to the automobile industry. Large steel producing operations were located near Detroit, providing the company with low shipping costs. Throughout the Great Depression, National Steel obtained profitability every year. The post-World War II years brought about record profits for the company as steel was in high demand.
