The 12% CrMoV series of steels can be regarded as a development of the original Harry Brearley cutlery grade. By adding nickel, molybdenum and vanadium to the basic 12% Cr grade, the strength is improved especially at high temperature. The key property is creep strength. Creep is the phenomenon where a material continues to deform with time under stress. For steels it is important to take account of creep above about 450°C. Typical steam temperatures for power generation are approximately 550°C which explains the extensive use of these grades in this application sector. Further enhancements of the 12% CrMoV grades have been developed with additions of tungsten, cobalt, niobium and nitrogen. These have often been known by brand names such as FV 448, FV 535, Jethete M152.
