The American Iron and Steel Institute, the industry trade organization formed in 1911 and led by U.S. Steel chairman Elbert Gary, helped spread many of U.S. Steel's policies and practices. An important effect of the corporation's dominance was its imposition of the Pittsburgh Plus pricing system upon the entire industry.
Transforming steel production. Iron is made by removing oxygen and other impurities from iron ore. When iron is combined with carbon, recycled steel and small amounts of other elements it becomes steel. Once made, it is a permanent resource; it is and infinitely recyclable without any loss of properties.

Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

1958, of 16 installations in the iron ore industry and 29 installations in the steel industry. Location of these installations are shown in figure 52. The mines and plants visited represent a cross section of the iron and steel industry with respect to geographic distribution, plant size, and processes used.
Iron has also been made by direct reduction. This method makes iron from high-grade ore without the use of a blast furnace, coke, or limestone. In one type of H-iron plant, hydrogen reduces the pulverized iron ore chemically. Reducing the oxygen is a step in ironmaking ordinarily done by burning coke in the blast furnace.
