X20CrMoV11-1, is a similar grade to X22CrMoV12-1, 1.4923 with a martensitic structure in the heat-treated state. Designed for pressure and high temperature applications up to 600 ℃ for devices used mainly in the power, oil and chemical industries.
Steel is mainly supplied in the form of hot-rolled boiler pipes, fittings and sleeves. In contrast to 23H12MNF, the above-mentioned grades shows much better and more stable strength properties in the normalized and tempered +NT conditions.
Steel can be classified as one of the heat-resistant grades.
