Zusammenfassung:The steel has the compsn. (by wt.) 0.08-0.14% carbon, 0.10-0.37% nickel, 0.5-0.7% molybdenum, 0.03-0.07% vanadium, 0.02-0.07% aluminium, 0.005-0.12% nitrogen, 0.003-0.012% phosphorus, 0.03-0.12% cerium, 0.001-0.006% antimony, balance iron the sum of the antimony and phosphorus contents being less than 0.011/(manganese content - 0.2). The steel is esp. useful for welded structures subjected to pressure, e.g. steam generators, volume compensators and other pressure vessels of 1-2 million kW nuclear power plant, where the structures have a thickness of 200-300 mm.
