EN10217-2 16Mo3 ERW Steel Pipe

16Mo3 welded pipe is a European standard pressure vessel steel pipe. 16Mo3 is pronounced as "sixteen molybdenum three steel," named according to its content of C (carbon) and Mo (molybdenum). This indicates that the carbon content of this steel plate is around 0.16, while the molybdenum content is around 3. 16Mo3 steel pipes contain a high molybdenum content, which provides heat resistance, making them suitable for high-temperature and high-pressure environments.

As a global steel pipe supplier, GNEE Group can provide you with 16Mo3 seamless pipes, 16Mo3 spiral welded pipes, 16Mo3 resistance welded pipes, 16Mo3 pressure vessel pipes, and more. If you have any requirements, please feel free to contact us at any time.

How Does the Sulphur (S) Element Affect the Weldability of 16Mo3 Welded Pipes?

Sulphur usually exists in steel in the form of iron sulphide, distributed in a network along the grain boundaries, thereby significantly reducing the toughness of the steel. The eutectic temperature of iron and iron sulphide is relatively low (985°C), so during hot processing, since the starting temperature is generally between 1150-1200°C, the iron and iron sulphide eutectic has already melted, leading to cracking during processing. This phenomenon is known as "sulphur-induced hot brittleness." This property of sulphur causes hot cracks during welding. Therefore, the sulphur content in steel is strictly controlled. The main difference between ordinary carbon steel, high-quality carbon steel, and premium quality steel lies in the amounts of sulphur and phosphorus they contain. As a professional steel pipe manufacturer, GNEE Group can provide ordinary carbon steel pipes and high-quality carbon steel pipes according to your requirements. If you have any needs, please contact us.
