DIN 17175 15Mo3 Alloy Steel Pipe
DIN 17175 15Mo3 alloy steel pipe is a seamless steel pipe produced in accordance with German Industrial Standards (DIN). It is mainly used for pressure equipment in high temperature environments, such as boilers and superheaters. This kind of steel pipe has excellent high temperature resistance and good mechanical properties, and is suitable for various high temperature and high pressure working environments.
The main chemical components of DIN 17175 15Mo3 alloy steel pipe include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and alloying elements such as chromium (Cr) and molybdenum (Mo). Among them, the addition of chromium and molybdenum improves the corrosion resistance and high-temperature strength of the steel pipe.
The following are some typical mechanical performance parameters of DIN 17175 15Mo3 alloy steel pipe:
Yield Strength: usually in the range of 310-480 MPa
Tensile Strength: Usually in the range of 480-630 MPa
Elongation: usually in the range of 20-22%
Impact Toughness: At -20°C, impact energy absorption is usually above 47 J
