What is steel and titanium

01 titanium steel is mainly composed of Fe, Cr, Ni, Mo, no titanium at all. Titanium steel is not a standard academic name, but a commercial name.

The so-called titanium steel is actually a kind of stainless steel, the main composition is Fe, Cr, Ni, Mo. No titanium. It's not titanium. It's 316L stainless steel. In business, it is called titanium steel, and some even titanium jewelry, which is actually stainless steel products without titanium. Jewelry made from the material sells for much less than other gold and silver jewelry.

Titanium was discovered at the end of the 18th century. In 1791, the British chemistry enthusiast W. Gregor discovered an unknown new element in the mineral. The element was discovered in 1795 by the German chemist M.H. Klaproth, who was studying rutile (TiO2) and named it after Titan, a child of the earth in Greek mythology (the Chinese name is titanium, a translation of its original name). In ancient Greece, the word "titania" was synonymous with courage, and the name Titanium was used to signify the natural strength of the metal.

Titanium (Ti)- silver gray metal, specific gravity 4.5, melting point 1668°C. Titanium is a very special metal, very light in texture, but also very strong and corrosion resistant, it will not turn black like silver, at room temperature to maintain its color for life. Titanium has a melting point similar to platinum, so it is often used in aerospace. Military precision components. When electric current and chemical treatment are added, different colors are produced. Due to the above properties of titanium, its characteristic silver gray tone is both highly polished. Both mercerization and matte have good performance, and are the most suitable jewelry metals except platinum and gold, which are often used in modern jewelry design abroad and are internationally popular jewelry materials. As for the design, the minimalist clean cutting, high design and low-key avant-garde style, highly praised by young white-collar workers. But because the processing technology of titanium is very demanding, it is difficult to cast with ordinary equipment, and it is difficult to weld it together with ordinary tools, so it is difficult to form a production scale. Therefore, it is difficult to see it in the domestic jewelry market.

There are many called titanium steel jewelry in China, the material is not titanium, is stainless steel, called titanium steel for attractive, some even called titanium alloy jewelry, is actually stainless steel jewelry without titanium.

Of stainless steel jewelry is the most common is called titanium steel material is 316 l stainless steel, and some manufacturers call the 316 l international standard titanium, actually is a kind of stainless steel 316 l number, is on the basis of 316 stainless steel to reduce the carbon content, expensive than ordinary stainless steel, corrosion resistance is very strong, suitable for skin contact act the role ofing is tasted. But can really long time almost no deformation discoloration, in common stainless steel, known as "titanium steel" 316L steel is the most suitable for jewelry.
