10CrMo910 alloy steel pipe is a 2.25Cr-1Mo pearlitic heat-resistant steel, a German grade widely used in the UK, US, Germany, Japan, and other countries. The seamless 10CrMo910 alloy pipe complies with the DIN 17175-1979 standard, which is equivalent to the domestic 12Cr2MoG (GB/T 5310 standard).
10CrMo910 alloy tubes are used for heating surface tubes in low- and medium-pressure boilers (operating pressure generally not exceeding 5.88 MPa, operating temperature below 450°C). They are also used for heating surface tubes, economizers, superheaters, reheaters, and petrochemical industry pipes in high-pressure boilers (operating pressure generally above 9.8 MPa, operating temperature between 450°C and 650°C).

Applications of DIN17175 10CrMo910 Heat-Resistant Seamless Steel Tube
Energy & Power:
Thermal Power Equipment: Used in key components of ultra-supercritical units, such as main steam pipelines (withstanding 32 MPa pressure), superheaters, and reheaters, ensuring the safe transportation of high-temperature and high-pressure steam.
Nuclear Power Systems: Serves as a coolant pipe material in nuclear islands, certified by ASME NQA-1, making it suitable for harsh nuclear environments.
Petrochemical Industry:
High-Temperature Pipelines: Transports media such as sour oil/gas and high-temperature steam, withstanding corrosive environments up to 560°C.
Reaction Equipment: Manufactures equipment like hydroprocessing reactors and heat exchangers, resisting erosion from complex chemical media.
Other Fields:
Aerospace: Used in high-temperature components such as aero-engine turbine blades and combustion chambers.
High-End Manufacturing: Precision cold-drawn tubes are used in hydraulic struts and fuel delivery systems, suitable for high-load operating conditions.
