Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Learn about the history, types, grades, and applications of steel, as well as its environmental impact and recycling.
Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world's infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.
Learn about the definition, production, types, properties, and uses of steel, the world's most important engineering and construction material. Find out how steel is recycled, environmentally friendly, and sustainable.
Learn about steel, a versatile and essential alloy of iron and carbon, with varying properties and applications. Explore the history, production, and recycling of steel, as well as its types and grades.
Steel is made of an alloy of iron and carbon in which the carbon content ranges up to 2 percent (with higher carbon content, the material is defined as cast iron). Iron, the major elemental component of steel, is one of the most plentiful elements in the earth's crust. All steel alloys are primarily iron and 0.002-2.1 % carbon by weight.
Learn about the four main types of steel (carbon, alloy, stainless, and tool) and their properties, usages, and classifications. Find the ASTM steel grade chart for various steel products and standards.
Learn the meaning, synonyms, examples, and history of the word steel, which can be a noun, verb, or adjective. Steel is a type of iron with carbon as an alloying element, and it can also refer to a hard quality or an industry.
Learn about the history, chemistry, and applications of iron and steel, the most common metals in the world. Find out how iron reacts with oxygen, carbon, and other elements to form different types of alloys.
Steel - Production, Uses, Types: The steel industry has grown from ancient times, when a few men may have operated, periodically, a small furnace producing 10 kilograms, to the modern integrated iron- and steelworks, with annual steel production of about 1 million tons. The largest commercial steelmaking enterprise, Nippon Steel in Japan, was responsible for producing 26 million tons in 1987 ...
Steel production began in bloomery furnaces thousands of years ago, but its industrial use began with the introduction of the blast furnace in the 17th century, which made crucible steel. Steel's mechanical properties determine whether it lasts long and efficiently in the most abrasive and wear-intensive applications or fails frequently or ...
