The 16Mo3 steel sheet is a pressure vessel steel manufactured in accordance with EN 10028-2. Specifically developed for elevated-temperature applications, it offers excellent heat resistance, high mechanical strength and reliable long-term performance. Thanks to its molybdenum alloying element, this steel grade maintains its mechanical properties even under continuous thermal stress. As a result, it is widely used in industrial plants where components operate under pressure and at high temperatures.
Sidastico supplies cut-to-size 16Mo3 steel sheets in a wide range of thicknesses and dimensions. Precision cutting ensures excellent dimensional accuracy, reduces material waste and simplifies subsequent fabrication processes. Every order is supplied with EN 10204 3.1 certification, guaranteeing full material traceability and compliance with European quality standards.
The material combines excellent weldability with very good fabrication properties. It is suitable for laser cutting, plasma cutting, bending and conventional manufacturing processes. Furthermore, its resistance to elevated temperatures makes it a reliable choice for equipment designed for continuous operation. Consequently, manufacturers benefit from long service life, consistent performance and dependable structural integrity in demanding environments.
Typical applications include boilers, pressure vessels, heat exchangers, steam pipelines, industrial furnaces and equipment used in the power generation, petrochemical and chemical industries. In addition, engineers select this steel grade whenever high temperature resistance, mechanical reliability and long-term durability are essential design requirements.
With extensive stock availability and advanced steel processing capabilities, Sidastico delivers cut-to-size 16Mo3 steel sheets with short lead times, consistent quality and reliable service. Every solution is tailored to meet the needs of demanding industrial applications while ensuring precision, efficiency and full compliance with international standards.
