Description

Introduce

X22CrMoV12-1, 1.4923 high-alloy structural steel is also classified as a heat-resistant steel - it is a martensitic-grade steel dedicated for parts, subassemblies and forgings of blades and parts of steam turbine rotors operating at temperatures up to 600 ℃.

Its application owes to its high resistance to fatigue stress. 1.4923 also features elements and parts of aircraft construction, components in the chemical, petrochemical and petrochemical industries, as well as parts used in the power industry.
