But it also reduces the amount of high carbon steel atmospheric corrosion resistance, high carbon steel in the open-air yard would easily corroded; In addition, the carbon can increase sensitivity to cold brittleness and aging steel. 2, silicon (Si): Si added as a reducing agent in the steel making process and deoxidizer, it killed steel containing 0.15-0.30% silicon. If the steel is more than 0.50-0.60% silicon, silicon even if alloying elements. Silicon can significantly improve the elastic limit of the steel, the yield point and tensile strength, it is widely used as a spring steel. Added 1.0-1.2% silicon in quenched and tempered steel, the strength can be increased by 15-20%. Silicon and molybdenum, tungsten, chromium, combined with improve corrosion resistance and antioxidant effects, can produce heat-resistant steel. Silicon 1-4% of low-carbon steel, with a high permeability, do silicon steel for electrical industry. Increase the amount of silicon will reduce weldability. 3, manganese (Mn): in steelmaking process, manganese is a good deoxidizer and desulfurizer, generally 0.30-0.50% manganese steel. In carbon steel added 0.70% or even "manganese", than the average amount of steel steel not only has enough toughness, and has high strength and hardness, improved hardenability of steel to improve the hot workability of steel, 40% higher than the A3 as 16Mn steel yield points. 11-14% manganese steels have high wear resistance, excavators bucket, ball mill liners and the like. Manganese content increased, reduced corrosion resistance of steel to reduce welding performance. 4, phosphorus (P): In general, phosphorus is harmful elements in steel, increased cold brittleness of steel, welding performance deterioration, lower ductility, so cold bending performance deterioration. So typically require phosphorus content in steel is less than 0.045%, high-quality steel requires lower. 304 stainless steel tube 5, sulfur (S): sulfur is usually harmful elements. Hot brittleness of the steel produced, reducing the ductility and toughness of the steel, causing cracks in the forging and rolling. Sulfur is also detrimental to the welding performance and reduce corrosion resistance. So often it requires a sulfur content of less than 0.055%, 0.040% or less than the requirements of high-quality steel. Join 0.08-0.20% sulfur in the steel can be improved machinability, commonly referred to cutting steel. 6, chromium (Cr): the structural steel and tool steel, chromium can significantly improve the strength, hardness and wear resistance, but at the same time reducing the ductility and toughness. Chrome steel can improve resistance to oxidation and corrosion resistance, so it is stainless steel, heat-resistant steel alloying elements important. 304 stainless steel tube 304 stainless steel tube 7, nickel (Ni): Ni can improve the strength of steel, while maintaining good ductility and toughness. Nickel acid have a higher corrosion resistance, high temperature anti-rust and heat resistance. But because the nickel is relatively scarce resources, it should be possible to use other alternative alloying elements nickel-chromium steel. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 8, molybdenum (Mo): Molybdenum makes grain refinement of steel to improve hardenability and thermal performance, maintain sufficient strength and creep resistance at high temperatures (in the long term subjected to stress at high temperature, deformation, called creep). Adding molybdenum steel, can improve the mechanical properties. It can also suppress the brittle steel due to the fire caused. In tool steel can improve red sex. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 9, titanium (Ti): Titanium is a strong deoxidizer in steel. It enables compact internal structure of steel, grain refinement force; reduce aging sensitivity and cold brittleness. Improve welding performance. Adding the appropriate titanium in nickel-chromium 18 9 austenitic stainless steel to avoid intergranular corrosion. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 10, vanadium (V): Vanadium is an excellent steel deoxidizer. Steel 0.5% of vanadium can be refined grains tissue, improve strength and toughness. Vanadium carbide and carbon formed at high temperature and pressure can increase resistance to hydrogen corrosion. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 11, tungsten (W): tungsten high melting point, specific gravity, is expensive raw alloying elements. Tungsten carbide with carbon has high hardness and wear resistance. Plus tungsten in tool steel, can significantly improve the red hardness and heat resistance, as cutting tools and forging mold. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 12, niobium (Nb): Nb can refine the grain and reduce heat sensitivity and temper brittleness of steel, increase strength, but ductility and toughness decrease. Niobium in an ordinary low alloy steel can improve the resistance to hydrogen, nitrogen, ammonia corrosion resistance to atmospheric corrosion and high temperature under. Niobium improves weldability. Increase in austenitic stainless steels, niobium, among prevents corrosion phenomenon. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 13, cobalt (Co): Cobalt is a rare precious metal, used for special steels and alloys, such as steel and heat resistant material. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 14, copper (Cu): Wuhan Iron and Steel Daye ore by the steel refining, often contain copper. Copper can improve the strength and toughness, especially atmospheric corrosion. The disadvantage is that during thermal processing prone to thermal embrittlement, significantly reduces the copper content exceeds 0.5% plastic. When the copper content is less than 0.50% no effect on weldability. 304 stainless steel tube 15, aluminum (Al): Aluminum is commonly used in steel deoxidizer. Adding a small amount of aluminum steel, refined grains can improve the toughness, such as deep-drawing steel sheet of 08Al. Aluminum also has antioxidant and anti-corrosion, aluminum and chromium, silicon combination, can significantly improve the ability of high-temperature steel can not afford leather performance and high temperature corrosion. The disadvantage is the effect of aluminum hot workability of steel, weldability and machinability properties. 16, boron (B): Boron steel can be improved by adding small amounts of dense and hot-rolled steel performance, increase strength. 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 304 stainless steel tube 17, nitrogen (N): N can improve the strength of steel, low-temperature toughness and weldability, increased sensitivity to aging. 18, RE (Xt): rare earth element refers to the Periodic Table of atomic number 57-71 15 lanthanides. These elements are metal, but their oxides are like "earth", so called rare earths is customary. Added steel rare earth, can change the composition of inclusions in steel, morphology, distribution, and nature, thereby improving the various properties of steel, such as toughness and weldability, cold workability. Plowshare adding rare earth in steel can improve the wear resistance. Stainless steel bar (round, square bar, hexagonal bar, angle, channel), specifications: ∮1mm-500MM.
