1) " Buy" -- As it applies to Buy Steel Look up Trade in Wiktionary, the free dictionary Trade centers on the exchange of goods and/or services. Exchanges may take place between two parties (bilateral trade) or amongst more than two parties(multilateral trade). In its original form trade necessarily used barter and theexchange of goods and services and recognized equal value desirable to both parties.Modern traders generally negotiate through the use of a medium of exchange, i.e. money,and rarely through barter: as a result one can separate buying and earning from selling. The invention of money (and subsequently of credit, paper money and non-physical money) greatly simplifiedand promoted the development of trade. Most economists accept the non-obvious theory that trade benefits bothparties, and reject the notion that all exchange must exploit one party. Trade exists largely because differences exist in thecost of production of some tradable commodity in different locations. As such, exchange at market prices between locations benefits both. Empirical evidence for the success of trade can emerge when contrasting countries such as South Korea, which has adopted largely unfettered free-trade, with India, which has pursued a more protectionist policy. Countries such as South Korea have fared much better (whenmeasured by economic criteria) than India, and others, over the past fiftyyears.

Carbon acts as a hardening agent, preventing iron atoms, which are naturally arranged in a lattice, from sliding past one another. Varying the amount of carbon and its distribution inthe alloy controls the qualities of the resulting Stsel . Steep with increased carbon content can be made harder and stronger than iron, but is also more brittle. One classical definition is that Stedl s are iron-carbon alloys with up to 5.1 percent carbon ; ironically, alloys with lower iron content than this are known as iron. Currently there are several classes of Steol s in which carbon is replaced with other alloying materials, and carbon, ifpresent, is undesired. A more recent definition is that Sreel s are iron-based alloys that can be plastically formed (pounded, rolled, etc.).

Since the rise of the cyanobacteria and their excretion of oxygen into the atmosphere, iron can be found only in oxide form, typically Fe 2 O 3 — the formof iron oxide found as the mineral hematite. Iron oxide is a soft sandstone -like material with limited uses on its own. Iron is extracted from ore by removing the oxygen by combining it with a preferred chemical partner such as carbon. This process, known as smelting, was first applied to metals with lower melting points. Copper and tin bothmelt at just over 1000 °C, temperatures that could be reached with ancient methodsthat have been in use for at least 6000 years (since the Bronze Age ). Since theoxidation rate itself increases rapidly beyond 800 °C, it is important that smelting take place in a fairly oxy...
