“12 Chrome Moly Van” steels are a series of martensitic stainless steels designed for use at moderately
1.4923 is a typical grade in this series. The dominant application is steam power generating plant.
This grade combines the following characteristics:
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.
Applications which illustrate these features include:
Pressure equipment, high temperature bolting, steam turbines, nuclear reactors, gas turbines, petroleum refining.
