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.

16Mo3 Steel Applications

Typical applications for 16Mo3 include a wide range of power plant equipment, industrial exhaust, venting and flare systems and waste recycling and incineration plants. It is also valuable for machinery where parts are likely to remain hot for an extended period.

In power plants it is regularly used in boilers, superheater tubes, collector and hot steam pipes, stove tubes and conduits. 16Mo3 is also used in various types of heat exchanger in both the upstream and downstream oil and gas industry

One example of how 16Mo3 plates is used is in the steel making process itself. The blast furnace requires plenty of hot air to convert the iron to steel and much of the output air is recovered and used to reheat the input and reduce costs. Traditionally the blast furnaces are made of standard carbon pressure vessel steels, but 16Mo3 provides a good alternative as it is more resistant to the huge thermal stresses that it undergoes on a daily basis. The 16Mo3 is also more resistant to the corrosion formed by nitrates as nitrogen oxide is removed from the steel mix. And this combination of properties can increase the life expectancy of critical plant equipment and reduce downtime.

For 16Mo3 heat resistance is provided by the 0.32% molybdenum alloying element.

16Mo3 Equivalents

It is equivalent to 15Mo3 (DIN 17155 – Germany), 15D3 (NFA 36–205 – France), BS1501–243b (BS1501 – UK) and ASTM 204 Gr.B. For customers requiring these grades we can offer 16Mo3 from stock.
