15Mo3 steel is a DIN specified pressure vessel grade chrome molybdenum steel alloy for use in elevated working temperatures.
15Mo3 steel is used as a weldable steel in the fabrication of industrial boilers and steel pressurised vessels found in the oil, gas and chemical industry. Due to the materials chrome and molybdenum content, 15Mo3 steel has excellent heat resistance and corrosion resistant characteristics.
