英文要約Title:Research and Development on Hydrogen Utilization Technology Research and Development on the Adjustment of Domestic Regulations, International Standard Harmonization and International Standardization for Fuel Cell Vehicles and Hydrogen Supply Infrastructure Research and Development on the Expansion of Utilizable Steel for Fuel Cell Vehicles and Hydrogen Stations (FY2013-FY2017) FY2016 Annual Report

The Japan Steel Works: Both the sustained-load cracking behavior and the fatigue limit of SNCM439 steel were measured in high-pressure gaseous hydrogen. Those test results and knowledge obtained were served to develop the “Technical document of low-alloy steels” with Task Force. The contents of the document includes the safety requirement of hydrogen storage tank for high pressure hydrogen service. Nippon Steel and Sumitomo Metal Corporation collaborated with Nippon Steel & Sumikin Stainless Steel Corporation: The applicability of two types of already-developed stainless steels for high pressure gaseous hydrogen were investigated. It was confirmed that the susceptibility to hydrogen gas embrittlement (HGE) of HRX19 weld joint was extremely low. Additionally, resistance to HGE increased with the addition of 0 to 3% Cu and 0.03 to 0.2% N in the case of 15Cr-9Mn-6Ni steel. It is considered that Cu and N suppress the formation of strain induced martensitic phase and the non-uniform strain concentration in the austenite phase. The Aichi Steel: AUS305-H(Ni-eq.>28.5) austenitic stainless steel for high pressure hydrogen use was developed for high pressure hydrogen valves and joints to optimize weight, cost and service life. Specimens for slow strain rate tensile tests were machined from forged products and hot-rolled bars. SSRT was carried out at 233K in 70MPa high pressure gaseous hydrogen. The resistance of the stainless steel to hydrogen gas embrittlement was revealed by the result of the tests. National Research Institute for Materials Science: Using a simple testing method with a hollow specimen in high-pressure hydrogen gas, the effects of hydrogen environment embrittlement (HEE) on tensile properties of the STH2 and HRX-19 at 70 MPa from 300 K to 190 K were evaluated. The relative reduction of area (RRA) of the STH2 was more than 0.8 even at 190 K, so there is small effect of HEE for STH2, even at low temperatures. The RRA of HRX-19 was more than 0.9 for those temperatures. The Japan Research Center for Metals: The experimental data of mechanical properties in hydrogen environment on the low alloy steels such as SCM435 and SNCM439 and the austenitic stainless steels such as HRX-19, STH-2 and AUS305-H were analyzed. The JRCM coordinated the JRCM group and also collaborated with the meetings hosted by the JPEC, the KHK, the Kyushu University and the JARI including two committees on the above data base.
