Abstract (en)
[origin: WO2013171277A1] An austenitic steel for hydrogen technology has the following composition: 0.01-0.4% by mass of carbon, <= 5% by mass of silicon, 0.3-30% by mass of manganese, 10.5-30% by mass of chromium, 4-12.5% by mass of nickel, <= 3% by mass of molybdenum, <= 0.2% by mass of nitrogen, <= 5% by mass of aluminum, <= 5% by mass of copper, <= 5% by mass of tungsten, <= 0.1% by mass of boron, <= 3% by mass of cobalt, <= 0.5% by mass of tantalum, <= 2% by mass of at least one of the elements: niobium, titanium, vanadium, hafnium and zirconium, <= 0.3% by mass of at least one of the elements yttrium, scandium, lanthanum, cerium and neodymium, remainder: iron and smelting-related steel-accompanying elements.
