Steel | Encyclopedia.comsteel Group of iron alloys containing a little carbon. The great strength of steel makes it an extremely important material in construction and manufacturing. The most common type is called plain carbon steel, because carbon is the main alloying material. This kind of steel usually contains less than 1% of carbon by weight.

Metallurgists | Article about Metallurgists by The Free ...Ferrous metallurgy encompasses the production of iron alloys (pig iron, steel, and ferroalloys). The production of ferrous metals accounts for 95 percent of the world metal production. Nonferrous metallurgy includes the production of most other metals. The production of radioactive metals is developing in connection with the use of atomic energy.
Properties, History, Production and Uses of BoronElemental boron is an allotropic semi-metal, meaning that the element itself can exist in different forms, each with its own physical and chemical properties. Also, like other semi-metals (or metalloids), some of boron's properties are metallic in nature while others are more similar to non-metals.
Ferrous metallurgy - WikipediaFerrous metallurgy is the metallurgy of iron and its alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from Sub-Saharan Africa to China.
