15CrMoG Alloy steel tube Introduction, characteristics, chemical composition, presentation method
15CrMoG Alloy steel pipe is a seamless steel tube, its performance is much higher than the general seamless steel pipe, because the inside of this tube contains CR more, its alloy steel tube high temperature, low-temperature, corrosion resistance of other seamless steel tubes, so the alloy tube in the petroleum, chemical, electric power, boiler and other industries are more widely used.
15CrMoG Alloy Steel Pipe The principle of purifying hydrogen from 15CrMoG alloy steel tube is that, at 300-500 ℃, hydrogen is adsorbed on the side of the 15CrMoG alloy steel tube, and the hydrogen is absorbed on the 1515CrMoG alloy steel pipe wall, because of the lack of two electrons in the 4d electron layer of palladium, It can produce unstable chemical bonds with hydrogen (this reaction of palladium and hydrogen is reversible), under the action of Palladium, hydrogen is ionized to proton its radius is 1.5x1015m, and the lattice constant of palladium is 3.88x10-10m (20 ℃), so it can pass 15CrMoG alloy steel pipe, Under the action of Palladium, protons are combined with electrons to form hydrogen molecules, escaping from the other side of the 15CrMoG alloy steel tube.

15CrMoG Alloy steel tube
In the 15CrMoG alloy steel tube surface, the gas is not dissociated from the transmission, so the use of 15CrMoG alloy steel tube to obtain high-purity hydrogen. Although palladium has a unique performance of hydrogen, but the mechanical properties of pure palladium, oxidation at high temperature, recrystallization temperature is low, easy to make 15CrMoG alloy steel tube deformation and embrittlement, it can not use pure palladium for the transmission of the membrane. Add the appropriate IB and Ⅷ family elements to palladium, palladium alloy can be used to improve the mechanical properties of PD. 11. Automobile half axle casing seamless steel pipe (gb3088-82) is a high quality carbon structural steel and alloy structure steel seamless steel tube, which is used to manufacture automobile axle casing and drive axle axle shell shaft, and the silver is about 20-30%,
The contents of other components (such as gold) are 5%.

15CrMoG Alloy steel Tube representation method
The two-digit number at the beginning of the ① steel represents the carbon content of the steel, expressed in a very extreme amount of carbon, such as 40Cr. The main alloying elements in ② steel, except for individual micro-alloying elements, are generally expressed in a few percent. When the average alloy content is <1.5%, the steel number in general only mark the element symbol, but does not indicate the content, but in the special situation is apt to confuse, after Yuansu may also mark with the numeral "1", for example steel number  "12crmov" and "12cr1mov", the former chromium content is 0.4-0.6%, The latter is 0.9-1.2% and the remainder is the same. When the alloying element average content ≥1.5%, ≥2.5%, ≥3.5% ... , the content should be indicated after the Yuansu, which can be expressed as 2, 3, 4 ... Wait。
such as 18cr2ni4wa. ③ Steel vanadium V, Ti ti, Al al, Boron B, re and other alloy elements, are micro-alloying elements, although the content is very low, still should be awarded in the steel number. For example, 20MnVB steel.
Vanadium is 0.07-0.12% and boron is 0.001-0.005%.
④ high-quality high-quality Steel should be in the final addition of the "a" to distinguish between the general high-quality steels. ⑤ Special-purpose alloy structural steel, with a steel number (or suffix) representing the use of this steel.
For example, the 30CrMnSi steel for riveting snail, the steel number is ml30crmnsi. 15CrMoG alloy steel pipe and seamless pipe both have relations and differences, can not be confused.
15CrMoG Alloy steel pipe is the production of materials (that is, material) to define, as the name implies is the alloy pipe, and seamless pipe is the steel pipe in accordance with the production process (seamless) to define, the difference between seamless pipe is a seam pipe, including straight seam welded pipe and spiral pipe.
