Application For high, middle, low pressure boiler and pressure purpose 15CrMoG alloy tube of the principles of the purified hydrogen at 300-500 ºC, the hydrogen to be purified is passed through one side of the 15CrMoG alloy tube, the hydrogen is adsorbed on 15CrMoG alloy wall, palladium 4d electron shell lacks two electronics, it can with the hydrogen generating unstable chemical bonds (palladium and hydrogen, this reaction is reversible), palladium, hydrogen is ionized proton whose radius is 1.5 × 1015m, while the lattice constant ofpalladium 3.88x 10-10M (20 ° C time), it can be through 15CrMoG alloy tube role of palladium proton combined with electronic and re-formation of the hydrogen molecules to escape from the other side of the 15CrMoG alloy tube.
In the 15CrMoG the surface of the alloy tube, not dissociated gas impermeable, can therefore be to use 15CrMoG alloy tube to obtain high purity hydrogen.

The standard applies to alloy structural steel bar 250mm maximum diameter or thickness. After consultation between the two sides of supply and demand, bar stock of diameter greater than 250 mm can also be provided The chemical compositions of steel grades specified in the standard also apply to steel ingot, billet and its productions.
The 15CrMo steel pearlite heat-resistant steel, high hot strength (δ b ≥ 440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. As the steel contains a higher content of Cr, C, and other alloying elements, the steel hardened tendency obvious, poor welding.
