GOST 17375 12Х1МФ Steel Elbow 12Kh1MF 12Cr1MoV
GOST 17375 12Х1МФ Elbow Manufaturer
GOST 17375 12Х1МФ Elbow is a seamless or welded pipe fitting designed for use in high-temperature and high-pressure service conditions, especially in boilers, power plants, and petrochemical piping systems. This material, 12Х1МФ (12Cr1MoV), is a low-alloy heat-resistant steel known for its excellent strength, oxidation resistance, and long-term performance at elevated temperatures up to 580°C.
