Stainless Steel for Hydrogen Stations
Hydrogen is the smallest element and makes metals brittle if infiltrating them. Steel materials used under a low-temperature and high-pressure hydrogen environment in hydrogen stations need to be varieties resistant to hydrogen embrittlement. We offer small lot and short-time delivery to meet hydrogen industry needs, by keeping in stock special stainless steel approved by the High Pressure Gas Safety Act. We also offer partly-finished fittings such as valves and joints, which are pre-processed by our own milling machines.
