Titanium is a strong deoxidizer in steel. It can make the internal structure of the steel compact, refine the grain force, and reduce the aging sensitivity and cold brittleness. Improve welding performance. Intergranular corrosion can be avoided by adding appropriate titanium to CR 18 Ni 9 austenitic stainless steel. The EMT pipe bender manufacturer tells us that vanadium is an excellent deoxidizer for steel. Adding 0.5% v to the steel can refine the grain structure and improve the strength and toughness. The carbides formed by vanadium and carbon can improve the hydrogen corrosion resistance at high temperature and high pressure.
By the way, I'd like to tell you that tungsten, with its high melting point and high specific gravity, is an alloy element of Guisheng. Tungsten carbide formed by tungsten and carbon has high hardness and wear resistance. Adding tungsten to tool steel can significantly improve the red hardness and heat strength. It can be used as cutting tool and forging die. Niobium can refine grain, reduce overheat sensitivity and temper brittleness, improve strength, but decrease plasticity and toughness. Adding niobium to ordinary low alloy steel can improve its resistance to atmospheric corrosion and hydrogen, nitrogen and ammonia corrosion at high temperature. Niobium can improve the weldability. Adding niobium to austenitic stainless steel can prevent intergranular corrosion.
EMT pipe bender manufacturers believe that everyone knows that cobalt is a rare and precious metal, which is mostly used in special steels and alloys, such as hot strength steels and magnetic materials. In WISCO, the steel made from Daye ore often contains copper. Copper can improve strength and toughness, especially atmospheric corrosion resistance. The disadvantage is that it is easy to produce hot embrittlement during hot working, and the plasticity decreases significantly when the copper content exceeds 0.5%. When the copper content is less than 0.50%, the weldability is not affected.
