Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels, which are resistant to corrosion and oxidation, typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, bicycles, machines, electrical appliances, furniture, and weapons.
Stainless steel, also known as inox or corrosion-resistant steel (CRES), is an alloy of iron that is resistant to rusting and corrosion. It contains at least 10.5% chromium and usually nickel, and may also contain other elements, such as carbon, to obtain the desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
United States Steel Corporation, more commonly known as U.S. Steel, is an American integrated steel producer headquartered in Pittsburgh, Pennsylvania, with production operations primarily in the United States of America and in Central Europe. The company produces and sells steel products, including flat-rolled and tubular products for customers in industries across automotive, construction, consumer, electrical, industrial equipment, distribution, and energy. Operations also include iron ore and coke production facilities.
Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures. As a result, tool steels are suited for use in the shaping of other materials, as for example in cutting, machining, stamping, or forging.
Weezer is the debut studio album by the American rock band Weezer, released on May 10, 1994, by DGC Records. It was produced by Ric Ocasek.
Steel is a metal alloy that is composed principally of iron and carbon.
William Justin Kroll was a Luxembourgish metallurgist. He is best known for inventing the Kroll process in 1940, which is used commercially to extract metallic titanium from ore.
Elbert Henry Gary was an American lawyer, county judge and business executive. He was a founder of U.S. Steel in 1901, bringing together partners J. P. Morgan, Andrew Carnegie, and Charles M. Schwab. The city of Gary, Indiana, a steel town, was named for him when it was founded in 1906. Gary, West Virginia was also named after him. When trust busting President Theodore Roosevelt said that Gary was head of the steel trust, Gary considered it a compliment. The two men communicated in a nonconfrontational way, unlike Roosevelt's communications with leaders of other trusts.
The United States Air Force Memorial honors the service of the personnel of the United States Air Force and its heritage organizations. The Memorial is located in Arlington County, Virginia, on the former grounds of the Navy Annex near The Pentagon and Arlington National Cemetery. The Memorial is southwest of the intersection of Columbia Pike and South Joyce Street and is accessible from the north side of Columbia Pike. It was the last project of American architect James Ingo Freed with the firm Pei Cobb Freed & Partners.
The SAE steel grades system is a standard alloy numbering system for steel grades maintained by SAE International.
The Steel Strike of 1919 was an attempt by the American Federation of Labor to organize the leading company, United States Steel, in the American steel industry. The AFL formed a coalition of 24 unions, all of which had grown rapidly during World War I. In the lead role would be the Amalgamated Association of Iron, Steel and Tin Workers (AA) with a five-member steering committee. The strike began on September 22, 1919, and finally collapsed on January 8, 1920. The opposition led by Elbert H. Gary, president of U.S. Steel had triumphed.
John P. Surma is an American businessman. He was the executive chairman of the board of United States Steel Corporation. Surma retired as CEO of U.S. Steel effective September 1, 2013, and Chairman effective January 1, 2014, positions he held since 2004.
W.R. Case & Sons Cutlery Company is an American manufacturer of traditional pocket knives, fixed blades/sporting knives, kitchen knives, limited edition commemoratives and collectibles. The company originated in Little Valley, New York, around the turn of the 20th century, before relocating to its current home, Bradford, Pennsylvania, in 1905. The company's namesake, William Russell Case, first made knives with his brothers under the name Case Brothers Cutlery Company. His son, John Russell ("Russ") Case, worked as a salesman for his father's company before founding W.R. Case & Sons.
Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. Stock bars and sheets of cold-rolled steel (CRS) are commonly used in all areas of manufacturing. The terms are opposed to hot-formed steel and hot-rolled steel.
Washington Steel Corporation was a highly successful post-war stainless steel production company, located in Washington, Pennsylvania. Washington Steel was the first U.S. company to use a Sendzimir Mill, invented by Polish inventor Tadeusz Sendzimir to cold-roll stainless steel.
SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium and nickel metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.
Crucible Industries, commonly known as Crucible, is an American company which develops and manufactures specialty steels, and is the sole producer of a line of sintered steels known as Crucible Particle Metallurgy (CPM) steels. The company produces high speed, stainless and tool steels for the automotive, cutlery, aerospace, and machine tool industries.
Kuppuswamy Anantha Padmanabhan is an Indian academician well known for his contributions in the field of materials & metallurgical science and engineering. In particular, he is well renowned for his contributions to superplasticity. He is currently professor of eminence (honorary), Anna University, Chennai; member, Research and Innovation Advisory Board, TCS and a research advisor to TCS and Aditya Birla S&T Company. He is a former director of Indian Institute of Technology Kanpur and a former dean, academic research, IIT Madras, India. In 1994, he became the first Indian to receive the "Forschungspreis" of the Alexander von Humboldt Foundation, Germany. For his research contributions, the University of Cambridge, UK, conferred on him the highest academic degree ‘Sc.D’ in 1998, and he is the first Indian engineer/ materials specialist to be conferred this honour. He also served as the Mercator Professor of DFG at the Institute of Materials Physics, University of Münster, Germany.
Ferritic stainless steel forms one of the five stainless steel families, the other four being austenitic, martensitic, duplex stainless steels, and precipitation hardened. For example, many of AISI 400-series of stainless steels are ferritic steels. By comparison with austenitic types, these are less hardenable by cold working, less weldable, and should not be used at cryogenic temperatures. Some types, like the 430, have excellent corrosion resistance and are very heat tolerant.
