The difference between titanium and titanium alloys and stainless steel
The density of titanium and titanium alloys is only 4.51, which is smaller than that of steel, only half the weight of steel, but its strength is similar to that of ordinary carbon steel. Titanium is a thermodynamically unstable metal and is very active. Titanium metal can form a natural oxide film (titanium dioxide) with the air. This stable, strong adhesion, and excellent protective oxide film determines the corrosion resistance of titanium. , so that titanium has excellent corrosion resistance, followed by light texture, high tensile strength, good mechanical properties is another excellent feature of titanium alloys.
Titanium alloys can be divided into: corrosion-resistant titanium alloys, structural titanium alloys, heat-resistant titanium alloys, and low-temperature titanium alloys.
1. It can be distinguished by color. Titanium is a bit dark, showing a cool color, which is cool, titanium is a little darker than steel. The steel is white, the pale kind. The two colors are clearly visible.
2. It can also be distinguished by chemical methods, that is, soak it with nitric acid. Titanium does not react, and stainless steel reacts strongly as soon as it is put down. The distinction between pure titanium and titanium alloys is difficult to see from the outside.
3. Titanium can draw gray-black marks on ceramic tiles, but stainless steel cannot.
4. Titanium has good corrosion resistance: it is easy to form a dense oxide film on the surface of titanium alloy below 550 ℃, so it is not easy to be further oxidized. Anti-loss things.
5. Titanium has good thermal strength: the melting point of titanium alloy is 1660℃, which is higher than that of iron.
6. Difficulty processing titanium: welding, electroplating and cold drawing are very difficult. Welding and electroplating must be carried out in vacuum or in the presence of inert gas (vacuum ion plating)
Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance and high heat resistance.
The density of titanium alloy is generally about 4.51g/cm3, which is only 60% of that of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials, see Table 7-1, and parts with high unit strength, good rigidity and light weight can be produced. Titanium alloys are used in aircraft engine components, skeletons, skins, fasteners and landing gear.
304 is a general-purpose stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. The density of stainless steel is 7.93 g/cm3, also known as 18/8 stainless steel. High temperature resistance of 800 degrees, has the characteristics of good processing performance and high toughness, and is widely used in industrial and furniture decoration industries and food and medical industries.
