"12 Chrome Moly Van” steels are a series of martensitic stainless steels designed for
use at moderately high temperatures. 1.4923 is a typical grade in this series.
The dominant application is steam power generating plant.
Martensitic steel grade EN 1.4923 DIN X22CrMoV12-1, Creep resisting steel,
hardened and tempered.
Usual upper temperature limit for continuous operating 580°C.
1.4923 grade combines the following characteristics:
-
Moderate strength – 800 MPa UTS, 600 MPa 0.2% PS at room temperature
-
Moderate high temperature strength – 280 MPa 0.2% PS at 550°C
-
Good creep strength – 137 MPa rupture stress at 550°C at 100000 hours
-
Moderate toughness – typically 50 J at room temperature
-
Basic corrosion resistance
-
Weldable with care. Requires pre and post weld heat treatment
Components featuring elevated high-temperature strength for use in thermal engines and power
plants, such as turbine blades, turbine discs, screws, bolts, pins and shafts.
