Alpha-phase titanium alloys areless ductile and have less strength than the beta-phasealloys, but have higher corrosion resistance anddeformability. Carbon is considered to be an impurity,commonly introduced during the manufacturingprocess, of commercially pure (CP) titanium grades.
Ferroalloys are alloys of iron that contain a high level of one or more other primary elements. The principle ferroalloys consist of silicon, manganese, and chromium that are used as vehicles to introduce the alloying element into the molten metal when making steel or cast iron. For example, silicon is used to deoxidize steel and as an alloying element in cast iron. Manganese is used as an alloying element and mitigates the harmful effects of sulfur in cast iron and steel. Chromium increases corrosion resistance in stainless steels. Since carbon is the most important alloying constituent in steel and cast iron production, and sulfur is a harmful contaminant that negatively affects the mechanical properties of steel and cast iron, the determination of carbon and sulfur levels in the ferroalloy feed stock is a critical quality control parameter.
