Alloying ElementsCategory: COMPOSITION AND PROPERTIES OF STEEL Commercial steels of even the simplest types are therefore primarily alloys of iron and carbon. Impurities and their remedies are always present: sulphur, phosphorus, silicon and manganese--to say nothing of oxygen, nitrogen and carbon oxide gases, about which we know very little. It has been found that other metals, if added to well-made steel, produce definite improvements in certain directions, and these alloy steels have found much use in the last ten years. Alloy steels, in addition to the above-mentioned elements, may commonly contain one or more of the following, in varying amounts: Nickel (Ni), Chromium (Cr), Vanadium (Va), Tungsten (W), Molybdenum (Mo). These steels will be discussed at more length in Chapters III and IV. Next: Properties Of Steel Previous: Manganese
