Steel Dynamics

	Steel Dynamics Steel Dynamics, Inc., sometimes abbreviated as "SDI", is an American steel producer based in Fort Wayne, Indiana. With a production capacity of 13 million tons of steel, the company is the third largest producer of carbon steel products in the United States. It is among the most profitable American steel companies in terms of profit margins and operating margin per ton. Based on its 2021 revenue, the company ranked 196th on the 2022 edition of the Fortune 500. History Steel Dynamics was founded in 1993 by three former executives of Nucor with $370 million in funding. It began production at its $275 million Butler, Indiana, flat roll mill in 1996 and reported its first annual profit in 1997. During the early 2000s recession, the company offered many incentive programs for employees to cut costs and improve standards and outperformed most other steel manufacturers. In 2007, the company acquired The Techs, three hot-dip galvanization plants in Pittsburgh that coat flat-rolled s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Public Company A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around . When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen ( O2) to form zinc oxide ( ZnO), which further reacts with carbon dioxide ( CO2) to form zinc carbonate ( ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle. It can be identified by the crystallization patterning on the surface (often called a "spangle"). Galvanized steel can be welded; however, one must exercise caution around the resulting toxic zinc fumes. Galvanized fumes are released when the galvanized metal reach ...

picture info	Steel Companies Of The United States Steel is an alloy made up of iron with added carbon to improve its strength of materials, strength and fracture toughness, fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high ultimate tensile strength, tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, Home appliance, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): Cubic crystal system, body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal lattice, crystal structure has relatively little resistance to the iron atoms slipping pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
