What is a 16mo3 Steel Plate?

16mo3 Steel Plate is a pressure vessel steel 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 various uses where the plates must continually perform at a high temperature. In addition, 16mo3 steel has good weldability and can be welded using conventional welding methods. Its physical properties make it suitable for high-pressure applications where increased strength of components is required, such as RHS pipes. The material offers good cold-forming characteristics plus excellent anti-corrosive properties due to its ability to form an effective barrier against corrosion caused by acid rain and other environmental elements. As such, 16mo3 Steel Plates are often used daily in construction projects and industries subjected to extreme conditions and harsh temperatures.

Composition of 16mo3 Steel Plates

16Mo3 steel plates have a composition that includes 0.30% carbon, 0.25-0.35% silicon, 0.90% manganese, and 0.035% phosphorus, along with other minor elements in trace amounts. Alloying elements such as molybdenum (1-1/2 to 6 %) and chromium (0.4 to 1%) are also present for added corrosion resistance purposes of 16Mo3 plates over the other types of steel available in the market. The physical properties of RHS pipes include tensile strength varying from 360 MPa to 480 MPa depending on thickness and yield strength ranging from 220 MPa to 275 MPa depending on diameter or thickness, respectively, and an elongation percentage usually exceeding 20%. With its high mechanical properties, this type of steel is extensively used in components where long-term performance under stress is needed, like pressure vessels and boilers built for hot liquids or gases carrying materials such as oil & gas at elevated temperatures around 400°C-500°C.

Properties of 16mo3 Steel Plates

One of the most significant benefits of 16mo3 Steel plates is their excellent tensile strength, which makes them ideal for high-temperature applications. The plates’ melting point is around 1300-1400℃, providing superior heat resistance. Additionally, 16mo3 Steel plates are corrosion-resistant, enhancing their durability and longevity. They are also ductile, ensuring ease of use during fabrication.

Maintenance of 16mo3 Steel Plates

To maintain optimal performance, 16mo3 Steel plates require careful maintenance. The plates must be thoroughly cleaned after each use to prevent corrosion. Following the manufacturer’s guidelines is crucial to ensure proper storage and transportation. Lubrication of the plates is necessary to ensure their ability to withstand the extreme temperatures they operate under.

Applications of 16mo3 Steel Plates

16mo3 Steel plates are predominantly used in power generation, the chemical industry, and boilers. The plates are also used for manufacturing pressure vessels, pipelines, and storage tanks that handle high-temperature substances. Their excellent heat-resistant properties make them a popular choice for thermal power stations, where they are used in steam turbines, coal conveyors, and burners. In chemical plants, 16mo3 Steel plates are used in reactors and pipes to transport liquids and chemicals.


In summary, 16mo3 Steel plates are an excellent choice for high-temperature applications due to their superior tensile strength, corrosion resistance, and heat resistance. The plates’ composition, properties, and maintenance requirements make them ideal for use in power plants, the chemical industry, and boilers. When handled with care, 16mo3 Steel plates can provide durability and longevity, ensuring maximum efficiency in the applications in which they are used.
