DIN17175 is the German steel pipe manufacturing standard, which specifies the technical requirements and test methods for specific types of steel pipes. 15Mo3 is a specific grade under this standard, representing a steel pipe with a specific chemical composition and mechanical properties.

DIN17175 15Mo3 steel pipe features:

 

The 15Mo3 steel pipe contains molybdenum, which makes it have better thermal strength while maintaining the same process properties as carbon steel. It has good resistance to high temperature and high pressure, suitable for a variety of harsh working environments. The manufacturing process of 15Mo3 steel pipe is strictly controlled to ensure its quality and performance are stable and reliable.

 

The chemical composition of DIN17175 15Mo3 steel pipe mainly includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P) and molybdenum (Mo). The proportions of these elements are precisely controlled to achieve the desired mechanical properties and corrosion resistance. The specific chemical composition range is roughly: C 0.12-0.20%, Si 0.10-0.35%, Mn 0.40-0.80%, S≤0.035%, P≤0.035%, Mo 0.25-0.35%.

 

DIN17175 15Mo3 steel pipe is usually delivered in a normal state, this state of steel pipe has better mechanical properties and hot processing properties. Depending on the specific order agreement, it is also possible to deliver in a non-processed state to meet the needs of different customers.

 

Due to its excellent high temperature and high pressure resistance, DIN17175 15Mo3 steel pipe is widely used in petroleum, chemical, power station, boiler and other industries. Specifically, it is commonly used in the production of reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drum, liquefied petroleum steam bottles, hydropower station high-pressure water pipes, water turbine volute and other equipment and components.
