Abstract Scope |
A compressed gas is the simplest solution for the storage and tranportation of hydrogen, so the most of hydrogen refueling stations (HRS) has adopted the high-pressure gaseous storage system. Because the tubes installed in HRS are exposed to hydrogens gas at high pressure of 87.5 MPa, STS316L seamless tubes are widely applied to prevent explosion as well as the hydrogen embrittlement. Due to the low strength of STS316L, however, the inner diameter of the tubes are less than 8 mm for 9/16 inches tubes, which could limit gas flow rate of HRS. Here we introduce the new alloy system and an effective fabrication process that can replace the STS316L seamless tubes. The seamless tubes with new alloys are fabricated by hot piercing process shows not only good mechanical properties of 850 MPa in strength and 35% elongation but also good resistance to the hydrogen embrittlement. |
