16Mo3 is a EN10028 specified pressure vessel grade chrome molybdenum steel alloy for use in elevated working temperatures.
The material 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, 16Mo3 has excellent heat resistance and corrosion resistant characteristics.
Grade 16Mo3 is available ex-stock from BBN steel and the material comes with test certification and stamping. Technical details are outlined in the data tables below.
The chemical composition of 16Mo3 Steel is given in the table below.
