CrMoV


CrMov is a low alloy ferritic steel.   Also known as a creep resisting alloy, this material is used in elevated temperature environment.  Base materials for the alloy provide creep rupture properties up to 580°C.  Developed in the 1970's, this material is typically used in fasteners and other parts for power plants.
