Introduction of the Scenario of How to Use Low Alloy Steels Safely in High Pressurized Hydrogen Gas

Description

<jats:p>In 2012, the Japanese regulation for selecting SUS316 austenitic stainless steel with a specific Ni equivalent (SUS316 and SUS316L can be used in the temperature ranges between −45 and 250 °C for a Ni equivalent of ≧28.5%, between −10 and 250 °C for a Ni equivalent of ≧ 27.4%, and between 20 and 250 °C for a Ni equivalent of ≧ 26.3%) as an appropriate material available in hydrogen refueling stations (HRSs) that provide 70 MPa fueling to fuel cell vehicles (FCVs) was updated with the support of NEDO (New Energy and Industrial Technology Development Organization) Program Phase 1 [1].</jats:p>
