16Mo3 steel plate/sheet is one mainly of Steel for boiler steels.EN10028 16Mo3 steel is mainly used for boilers and pressure vessels with elevated temperatures equivalent to DIN17155 15Mo3 and UNI5869 15M03, 15D3 (NFA 36205 ) and ASTM A204Gr.B.
16Mo3 steel is a pressure vessel steel that is used in applications with elevated temperatures according to EN 10028–2. It has improved mechanical properties and better creep resistance allowing it to be used up to 500°C. This makes it ideal for a wide range of uses where the plates will have to perform at a high temperature continuously.
The material is used as a weldable steel in the fabrication of industrial boilers and steel pressurized vessels found in the oil, gas and chemical industry. Due to the materials chrome and molybdenum content, 16Mo3 has excellent heat resistance and corrosion resistant characteristics.
