COST REDUCED STEEL FOR HYDROGEN TECHNOLOGY WITH HIGH RESISTANCE TOHYDROGEN INDUCED EMBRITTLEMENT

摘要

A corrosion-resistant, hot and cold formable and weldable steel for use in hydrogen-induced technology with high resistance to hydrogen embrittlement has the following composition: 0.01 to 0.4 percent by mass of carbon, ≦̸3.0 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, ≦̸1.0 percent by mass of molybdenum, ≦̸0.2 percent by mass of nitrogen, 0.5 to 8.0 percent by mass of aluminum, ≦̸4.0 percent by mass of copper, ≦̸0.1 percent by mass of boron, ≦̸1.0 percent by mass of tungsten, ≦̸5.0 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.
