Product Description<\/p>\n

The alloying elements can change and personalize properties-their flexibility, strength, formability, and hardenability.As a guideline, alloying elements are added in lower percentages (less than 5%) to increase strength or hardenability, or in larger percentages (over 5%) to achieve special properties, such as corrosion resistance or extreme temperature stability.\u00a0Manganese, silicon, or aluminium are added during the\u00a0steelmaking\u00a0process to remove dissolved\u00a0oxygen,\u00a0sulfur\u00a0and\u00a0phosphorus\u00a0from the\u00a0melt. Manganese, silicon,\u00a0nickel, and copper are added to increase strength by forming CHINAMFG solutions in ferrite. Chromium, vanadium, molybdenum, and tungsten increase strength by forming second-phase\u00a0carbides. Nickel and copper improve corrosion resistance in small quantities. Molybdenum helps to resist embrittlement. Zirconium, cerium, and calcium increase toughness by controlling the shape of inclusions. Sulfur (in the form of\u00a0manganese sulfide), lead, bismuth, selenium, and tellurium increase machinability.The alloying elements tend to form either CHINAMFG solutions or compounds or carbides. Nickel is very soluble in ferrite; therefore, it forms compounds, usually Ni3<\/sub>Al. Aluminium dissolves in the ferrite and forms the compounds Al2<\/sub>O3<\/sub>\u00a0and AlN. Silicon is also very soluble and usually forms the compound SiO2<\/sub>\u2022Mx<\/sub>Oy<\/sub>. Manganese mostly dissolves in ferrite forming the compounds MnS, MnO\u2022SiO2<\/sub>, but will also form carbides in the form of (Fe,Mn)3<\/sub>C. Chromium forms partitions between the ferrite and carbide phases in steel, forming (Fe,Cr3<\/sub>)C, Cr7<\/sub>C3<\/sub>, and Cr23<\/sub>C6<\/sub>. The type of carbide that chromium forms depends on the amount of carbon and other types of alloying elements present. Tungsten and molybdenum form carbides if there is enough carbon and an absence of stronger carbide forming elements (i.e.,\u00a0titanium\u00a0&\u00a0niobium), they form the carbides W2<\/sub>C and Mo2<\/sub>C, respectively. Vanadium, titanium, and niobium are strong carbide forming elements, forming\u00a0vanadium carbide,\u00a0titanium carbide, and\u00a0niobium carbide, respectively.Alloying elements also have an effect on the eutectoid temperature of the steel. Manganese and nickel lower the eutectoid temperature and are known as\u00a0austenite stabilizing elements. With enough of these elements the austenitic structure may be obtained at room temperature. Carbide-forming elements raise the eutectoid temperature; these elements are known as\u00a0ferrite stabilizing elements. <\/p>\n
