X22CrMoV12-1 / EN 1.4923 Alloy Steel Supplier – Properties, Composition, Equivalents & Applications 

For critical high-temperature and high-pressure service, material selection is paramount. X22CrMoV12-1 alloy steel, also designated as EN 1.4923, is a premier martensitic heat-resistant steel engineered for these demanding environments. This chromium-molybdenum-vanadium steel provides an exceptional combination of high-temperature strength, long-term creep resistance, and stability, making it a cornerstone material for power generation and petrochemical applications. 

The 1.4923 steel grade maintains its mechanical integrity at temperatures up to approximately 600°C (1112°F). Its unique alloying composition enables it to withstand continuous operational stresses over extended periods without significant deformation or failure. This makes it an indispensable choice for components in steam turbines, power plant boilers, superheaters, and high-pressure piping systems where reliability and long service life are non-negotiable. If your operations involve high-temperature alloy steel, understanding the specific benefits of X22CrMoV12-1 is essential for optimizing performance and safety.
