Alloying Elements






Category: 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.
