X22CrMoV12-1 1.4923 Martensitic Creep Resisting Stainless Steel
Introduction and Applications
FUSHUN SPECIAL STEEL, as a professional stainless steel manufacturer, is proud to supply high-quality X22CrMoV12-1 (1.4923) martensitic creep resisting stainless steel. This premium grade steel is specifically engineered for demanding high-temperature applications where exceptional mechanical strength and creep resistance are essential requirements.
X22CrMoV12-1 stainless steel is a heat-treatable martensitic grade containing a carefully balanced combination of chromium, molybdenum, vanadium, and nickel elements. This steel grade demonstrates excellent performance at elevated temperatures up to 580°C (1076°F), making it ideal for critical components in power generation and industrial applications. The material is typically produced and heat treated according to QT800 specification, ensuring optimal mechanical properties at both room temperature and elevated operating temperatures.
Primary Applications
Turbine blades, steam turbine components, and power plant equipment operating at elevated temperatures.
Pressure vessels, boilers, and high-temperature fasteners for industrial processing systems.
Aviation components and aerospace applications requiring high strength at elevated temperatures.
Reactor manufacturing and chemical production facility components exposed to high temperatures.
Chemical Composition of X22CrMoV12-1 (1.4923)
The carefully balanced chemical composition of 1.4923 steel ensures optimal creep resistance and mechanical properties at high temperatures. As a trusted manufacturer, FUSHUN SPECIAL STEEL maintains strict control over all alloying elements during the melting process.

Heat Treatment Guidelines
Proper heat treatment is essential for achieving optimal mechanical properties in X22CrMoV12-1 steel. As a manufacturer with complete in-house heat treatment capabilities, FUSHUN SPECIAL STEEL ensures precise temperature control and consistent results for every batch.
Annealing (+A)
Heat to 750-800°C, hold for adequate time based on section thickness, then furnace cool slowly. This process reduces hardness and improves machinability.
Hardening (Quenching)
Heat to 1020-1070°C, hold until uniformly heated through the section, then oil quench or air cool. Preheating at 650-700°C is recommended for large sections.
Tempering
Temper at 680-750°C for QT800 condition. Hold time depends on section size (minimum 2 hours). Air cool after tempering. Double tempering may be beneficial.
Stress Relieving
Heat to 650-700°C (below tempering temperature), hold for 1-2 hours per 25mm of thickness, then furnace cool or air cool slowly.
