 Detection / Consulting: 180-2871-9376 (Wang Li) QQ: 2419906857 beneficial elements manganese steel, silicon, vanadium, titanium, etc., can be controlled incorporation into low-alloy steel smelting. Steel main harmful elements sulfur, phosphorus and oxygen, paying particular attention to control its content. Phosphorus is one of very harmful elements in steel, mainly soluble ferrite from strengthening. Phosphorus content increases, the strength of steel, hardness, ductility and toughness decrease significantly. In particular, the lower the temperature, on the greater plasticity and toughness, thereby significantly increasing cold brittleness of steel. Phosphorus also can significantly reduce the steel weldability, but phosphorus can improve the wear resistance and corrosion resistance of steel. Sulfur is also very harmful elements, nonmetal sulfide inclusions were present in the steel, lowering of various mechanical properties of the steel. Because of the low melting point sulfide, resulting in separation of the steel in the thermal processing of grains, causing fracture of steel, the formation of thermal embrittlement phenomenon known as hot brittleness. Sulfur steel weldability, toughness, fatigue resistance and corrosion resistance etc. is reduced. Oxygen is harmful elements in steel, mainly in the non-metallic inclusions, small amounts of melt in ferrite. Non-metallic inclusions reduce the mechanical properties of steel, especially toughness. Oxygen has a tendency to promote the role of aging. Low melting point oxides caused also weldability of the steel is deteriorated.
