Alloy Steel Seamless Tube DIN17175 13CrMo44 Boiler Tube of Heat resistant Steels
DIN 17175 is a German standard for seamless and welded steel tubes used in high-temperature applications. The standard specifies requirements for tubes used in industries like power plants, chemical plants, and boiler manufacturing, particularly where the tubes are exposed to high temperatures and pressures.
13CrMo44 refers to a specific grade of steel within that standard:
-
13: Indicates the main alloying element, which is Chromium (Cr), typically around 1.5%–2.5%. Chromium improves the material's resistance to oxidation and corrosion, especially at elevated temperatures.
-
Cr: Stands for Chromium, as mentioned above.
-
Mo: Refers to Molybdenum, which is added to improve high-temperature strength and resistance to creep.
-
44: Refers to the material’s nominal carbon content, which is around 0.44%.
Key properties of 13CrMo44 steel tube:
-
High temperature resistance: Suitable for applications in high-pressure systems and environments with temperatures up to 580°C (1076°F).
-
Corrosion resistance: The chromium content gives it enhanced resistance to oxidation and corrosion.
-
Strength: Molybdenum adds to its strength and resistance to thermal creep, making it ideal for power plant boilers, heat exchangers, and other high-stress environments.
Common applications:
It's a steel that combines durability, high-temperature resistance, and corrosion resistance, making it well-suited for industrial applications where heat and pressure are a concern.
