EN10028-2 16Mo3 Boiler and Pressure Vessel Steel Plates

EN10028-2 16Mo3 steel plates are widely used in the fabrication of boilers and pressure vessels due to their excellent mechanical properties and resistance to high-temperature environments. This grade is particularly suited for applications where high resistance to pressure and heat is required, such as in power plant equipment, petrochemical industry, and oil refineries.
Chemical Composition:
The chemical composition of 16Mo3 is carefully balanced to provide the necessary strength and toughness while maintaining good weldability. The typical chemical composition is as follows:

• Carbon (C): ≤ 0.18%
• Silicon (Si): ≤ 0.35%
• Manganese (Mn): 0.60 – 1.20%
• Phosphorus (P): ≤ 0.025%
• Sulfur (S): ≤ 0.010%
• Chromium (Cr): 0.30 – 0.80%
• Molybdenum (Mo): 0.25 – 0.35%
• Nickel (Ni): ≤ 0.30%
• Aluminum (Al): ≥ 0.020%

Mechanical Properties:
The mechanical properties of 16Mo3 are characterized by high tensile strength and good ductility, which are essential for the safety and reliability of pressure equipment. Typical mechanical properties include:

• Yield Strength: ≥ 275 MPa
• Tensile Strength: 480 – 620 MPa
• Elongation: ≥ 22%
• Impact Energy (at -20°C): ≥ 40 Joules

Heat Treatment:
16Mo3 steel plates are generally supplied in a normalized condition. Normalization is a heat treatment process that refines the grain structure and improves the mechanical properties of the steel. The plates can also be supplied in a normalized and tempered condition upon request.
Available Dimensions:
TJC Steel Group offers 16Mo3 steel plates in a wide range of sizes to meet the diverse needs of our customers. The typical available dimensions are:

• Thickness: 6 – 150 mm
• Width: 1500 – 3500 mm
• Length: 3000 – 12000 mm

Low-Temperature Impact Test:
16Mo3 steel plates are subjected to a low-temperature impact test to ensure their toughness at sub-zero temperatures. The test is conducted at -20°C, and the material must meet the specified impact energy requirements to pass.
Main Applications:
The primary applications of 16Mo3 steel plates include:

• Boilers
• Pressure vessels
• Heat exchangers
• Steam lines
• Petrochemical equipment
• Nuclear power plants
