🔹 About DIN 1.4903 Steel

DIN 1.4903, also known as X10CrMoVNb9-1 or Grade 91, is a martensitic creep-resistant alloy steel designed for high-temperature and high-pressure applications. Its unique alloying with chromium, molybdenum, vanadium, and niobium ensures long-term strength, creep resistance, and thermal stability.

Applications include boilers, power plants, turbines, heat exchangers, and petrochemical piping systems.
