16Mo3 Alloy Steel Plate for High-Temperature Pressure Equipment

When buyers source 16Mo3 Alloy Steel Plate, the focus is usually not on ultra-high strength, but on reliable performance under continuous elevated temperatures. Manufactured according to EN 10028-2, 16Mo3 is a pressure vessel steel with molybdenum alloying that offers improved heat resistance over ordinary carbon steel. It is widely selected for boilers, heat exchangers, steam pipelines and pressure vessels operating up to approximately 530°C.

Why Many Pressure Equipment Manufacturers Choose 16Mo3?

Stable Strength at Elevated Temperature

The addition of 0.25–0.35% Mo helps maintain mechanical properties during long-term service at high temperatures, making it suitable for boilers and thermal equipment.

Better Creep Resistance than Carbon Steel

Compared with standard structural steels, 16Mo3 provides improved creep resistance, reducing deformation during continuous high-temperature operation.

Good Fabrication Performance

The plate can be cut, welded and formed using conventional fabrication methods. Proper preheating is recommended for thicker sections to achieve consistent weld quality.

Widely Accepted European Pressure Vessel Material

Because it complies with EN 10028-2, 16Mo3 is commonly specified for European industrial projects, helping simplify material approval and documentation.
