Ledeburite (ferrite-cementite eutectic, 4.3% carbon)
Cementite (iron carbide, Fe 3C) Alloys with a higher carbon content are known as cast iron because of their lower melting point and castability.[1] Steel is also distinguished from wrought iron, which can contain a small amount of carbon, but it is included in the form of slag inclusions. Two distinguishing factors are steel's increased rust-resistance and better weldability. Though steel had been produced by various inefficient methods long before the Renaissance, its use became more common after more efficient production methods were devised in the 17th century. With the invention of the Bessemer process in the mid-19th century, steel became a relatively inexpensive mass-produced material. Further refinements in the process, such as basic oxygen steelmaking, further lowered the cost of production while increasing the quality of the metal. Today, steel is one of the most common materials in the world and is a major component in buildings, infrastructure, tools, ships, automobiles, machines, and appliances. Modern steel is generally identified by various grades of steel defined by various standards organizations. Iron, like most metals, is found in the Earth's crust only in the form of an ore, ie. combined with other elements such as oxygen or sulfur.[2] Typical iron-containing minerals include Fe2O3—the form of iron oxide found as the mineral hematite, and FeS2—pyrite (fool's gold).[3] Iron is extracted from ore by removing oxygen and combining the ore with a preferred chemical partner such as carbon. This process, known as smelting, was first applied to metals with lower melting points, such as tin, which melts at approximately 250&_160;°C (482&_160;°F) and copper, which melts at approximately 1,000&_160;°C (1,830&_160;°F). In comparison, cast iron melts at approximately 1,370&_160;°C (2,500&_160;°F). All of these temperatures could be reached with ancient methods that have been used since the Bronze Age. Since the oxidation rate itself increases rapidly beyond 800 °C, it is important that smelting take place in a low-oxygen environment. Unlike copper and tin, liquid iron dissolves carbon quite readily. Smelting results in an alloy (pig iron) containing too much carbon to be called steel.[4] The excess carbon and other impurities are removed in a subsequent step.
