TA1 pure titanium tube

 

Industrial pure titanium is divided into three grades of TA1, TA2 and TA3 according to their impurity content. The gap impurity elements of these three kinds of industrial pure titanium are gradually increased, so their mechanical strength and hardness also increase step by step, but the plasticity and toughness decrease accordingly.
The industrial pure titanium commonly used in industry is TA2, because its corrosion resistance and comprehensive mechanical properties are moderate. TA3 can be used when the requirements for wear resistance and strength are high. TA1 can be used when better molding performance is required.
TA1, TA2 and TA3 in the national standard correspond to Gr0, Gr1 and Gr2 in this UNS.
TA1 and TA2 have good low temperature toughness and high low temperature strength when the iron content ω is 0.095%, the oxygen content ω is 0.08%, the hydrogen content ω is 0.0009%, and the nitrogen content ω is 0.0062%. -Low temperature structural materials below 253 ℃.

 

TA2 chemical composition: TA2 contains titanium (Ti) balance, iron (Fe) ≤0.30, carbon (C) ≤0.10, nitrogen (N) ≤0.05, hydrogen (H) ≤0.01 5, oxygen (O) ≤0.25.

Titanium alloy is an alloy composed of titanium added with other elements. Titanium has two kinds of heterogeneous crystals: below 882 ℃ is a close-packed hexagonal structure α titanium, above 882 ℃ is a body-centered cubic β titanium.

 

Alloying elements can be divided into three categories according to their influence on the phase transition temperature:
①The elements that stabilize the α phase and increase the phase transition temperature are α stable elements, including aluminum, carbon, oxygen and nitrogen. Among them, aluminum is the main alloy element of titanium alloy, which has a significant effect on improving the normal temperature and high temperature strength of the alloy, reducing the specific gravity, and increasing the elastic modulus.
②The element that stabilizes the β phase and lowers the phase transition temperature is the β stable element, and can be divided into two types: isomorphic and eutectoid. The former has molybdenum, niobium, vanadium, etc .; the latter has chromium, manganese, copper, iron, silicon, etc.
③The elements that have little effect on the phase transition temperature are neutral elements, such as zirconium and tin.
Oxygen, nitrogen, carbon and hydrogen are the main impurities of titanium alloys. Oxygen and nitrogen have greater solubility in the α phase, which has a significant strengthening effect on titanium alloys, but reduces the plasticity. Generally, the content of oxygen and nitrogen in titanium is 0.15 to 0.2% and 0.04 to 0.05%, respectively. The solubility of hydrogen in the α phase is very small. Too much hydrogen dissolved in the titanium alloy will produce hydride and make the alloy brittle. Usually the hydrogen content in titanium alloy is controlled below 0.015%. The dissolution of hydrogen in titanium is reversible and can be removed by vacuum annealing.
Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. In addition, the titanium alloy has poor process performance and is difficult to cut. In hot working, it is very easy to absorb impurities such as hydrogen, oxynitride and carbon. There is also poor abrasion resistance and complicated production process. The industrial production of titanium began in 1948. The need for the development of the aviation industry has enabled the titanium industry to grow at an average annual growth rate of about 8%. The world's annual output of titanium alloy processed materials has reached more than 40,000 tons, and there are nearly 30 types of titanium alloys. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).
Titanium is a new type of metal. The performance of titanium is related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. The purity of titanium iodide does not exceed 0.1%, but its strength is low and its plasticity is high. The properties of 99.5% industrial pure titanium are: density ρ = 4.5g / cubic centimeter, melting point 1725 ℃, thermal conductivity λ = 15.24W / (mK), tensile strength σb = 539MPa, elongation δ = 25%, cross section Shrinkage ψ = 25%, elastic modulus E = 1.078 × 105MPa, hardness HB195.

 

high strength
The density of titanium alloy is generally about 4.51g / cubic centimeter, which is only 60% 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 greater than other metal structural materials, and parts with high unit strength, good rigidity and light weight can be produced. Titanium alloys are used for aircraft engine components, skeletons, skins, fasteners, and landing gear.

 

High thermal strength
The use temperature is several hundred degrees higher than that of aluminum alloy. It can still maintain the required strength at moderate temperature. It can work for a long time at a temperature of 450 ~ 500 ℃. These two types of titanium alloys are still very high in the range of 150 ℃ ~ 500 ℃. Specific strength, while the specific strength of aluminum alloy at 150 ℃ significantly decreased. The working temperature of titanium alloy can reach 500 ℃, aluminum alloy is below 200 ℃.

 

Good corrosion resistance
Titanium alloys work in humid atmosphere and seawater media, and their corrosion resistance is far superior to stainless steel; they are particularly resistant to pitting, acid corrosion, and stress corrosion; organic materials such as alkali, chloride, chlorine, nitric acid, and sulfuric acid Etc. have excellent corrosion resistance. However, titanium has poor corrosion resistance to media with reducing oxygen and chromium salts.

 

Good low temperature performance
Titanium alloys can still maintain their mechanical properties at low and ultra-low temperatures. Titanium alloys with good low temperature performance and extremely low interstitial elements, such as TA7, can maintain a certain plasticity at -253 ℃. Therefore, titanium alloy is also an important low-temperature structural material.

 

Great chemical activity
Titanium is chemically active and produces strong chemical reactions with O, N, H, CO, CO2, water vapor, ammonia, etc. in the atmosphere. When the carbon content is greater than 0.2%, hard TiC will be formed in the titanium alloy; when the temperature is high, the TiN hard surface layer will be formed when it interacts with N; above 600 ℃, titanium absorbs oxygen to form a hardened layer with high hardness ; Increased hydrogen content will also form a brittle layer. The depth of the hard and brittle surface produced by absorbing gas can reach 0.1 ~ 0.15 mm, and the degree of hardening is 20% ~ 30%. Titanium also has a large chemical affinity, which tends to cause adhesion to friction surfaces.

Titanium tubes implement two national standards according to different requirements and performance: GB / T3624-2010GB / T3625-2007 ASTM 337 338
