Reduced cost steel for hydrogen technology with high resistance to hydrogen-induced embrittlement

摘要

An austenitic steel for hydrogen technology has the following composition:0.01 to 0.4 percent by mass of carbon,≤5 percent by mass of silicon,0.3 to 30 percent by mass of manganese,10.5 to 30 percent by mass of chromium,4 to 12.5 percent by mass of nickel,≤3 percent by mass of molybdenum,≤0.2 percent by mass of nitrogen,≤5 percent by mass of aluminum,≤5 percent by mass of copper,≤5 percent by mass of tungsten,≤0.1 percent by mass of boron,≤3 percent by mass of cobalt,≤0.5 percent by mass of tantalum,≤2.0 percent by mass of at least one of the elements: niobium, titanium, vanadium, hafnium and zirconium,≤0.3 percent by mass of at least one of the elements: yttrium, scandium, lanthanum, cerium and neodymium, the remainder being iron and smelting-related steel companion elements.
