16Mo3 Pressure Vessel Steel Plate is a low-alloy molybdenum steel specified under EN 10028-2, with material number 1.5415. It is primarily used in the manufacture of boilers, pressure vessels, heat exchangers and industrial equipment operating at elevated temperatures.
For industrial pressure tank manufacturing, 16Mo3 steel plate provides specified mechanical properties at temperatures up to 500°C. Its molybdenum content of 0.25–0.35% contributes to its elevated-temperature performance.
However, the maximum allowable operating temperature of a finished pressure vessel must be determined according to the applicable design code, operating pressure, material thickness and design life.
Gnee supplies 16Mo3 pressure vessel steel plates for international industrial equipment projects, supporting customized dimensions, steel plate processing, material inspection and bulk export requirements.

Mechanical Properties of 16Mo3 Steel Plate by Thickness
For pressure vessel manufacturers, plate thickness directly affects the specified minimum yield strength of 16Mo3 steel.
According to published EN 10028-2:2017 plate data, the minimum yield strength decreases from 275 MPa for plates up to 16 mm thick to 220 MPa for plates over 100 mm and up to 150 mm thick.
| Thickness (mm) | Min. Yield Strength (MPa) | Tensile Strength (MPa) |
|---|---|---|
| 5–16 | 275 | 440–590 |
| >16–40 | 270 | 440–590 |
| >40–60 | 260 | 440–590 |
| >60–100 | 240 | 430–580 |
| >100–150 | 220 | 420–570 |
These values apply to the specified material and delivery conditions.

Elevated-Temperature Properties of 16Mo3 Steel Plate
For industrial tanks operating at elevated temperatures, room-temperature tensile properties alone are insufficient for material selection.
The following table shows the specified minimum 0.2% proof strength of 16Mo3 steel plate at different temperatures and thicknesses.
Minimum 0.2% Proof Strength (MPa)
| Temperature | 5–16 mm | >16–40 mm | >40–60 mm | >60–100 mm |
|---|---|---|---|---|
| 100°C | 264 | 259 | 250 | 230 |
| 150°C | 250 | 245 | 236 | 218 |
| 200°C | 233 | 228 | 220 | 203 |
| 250°C | 213 | 209 | 202 | 186 |
| 300°C | 194 | 190 | 183 | 169 |
| 350°C | 175 | 172 | 165 | 153 |
| 400°C | 159 | 156 | 150 | 139 |
For example, a 20 mm 16Mo3 steel plate has a specified minimum 0.2% proof strength of 259 MPa at 100°C. At 400°C, this value decreases to 156 MPa, representing a reduction of approximately 39.8%.
This illustrates why the actual design temperature must be provided when selecting 16Mo3 pressure vessel steel plate.
Applications of 16Mo3 Steel Plate in Industrial Tanks
16Mo3 pressure vessel steel plate is suitable for consideration in pressure-retaining equipment where elevated-temperature mechanical properties are required.
| Application | Typical Components |
|---|---|
| Pressure Vessels | Shells and heads |
| High-Temperature Process Tanks | Pressure-retaining shells |
| Heat Exchangers | Shells and pressure components |
| Boiler Equipment | Pressure-retaining components |
| Industrial Processing Vessels | Welded vessel components |
Unlike ordinary atmospheric storage tanks, high-temperature pressure vessels require material selection based on the actual combination of temperature, pressure and design requirements.
For corrosive media, additional material compatibility assessments are necessary. 16Mo3 is not inherently a corrosion-resistant substitute for stainless steel.
How to Calculate 16Mo3 Steel Plate Procurement Weight
For international pressure vessel projects, calculating the theoretical weight of steel plates helps buyers estimate procurement quantities, packaging requirements and transportation arrangements.
The following examples use a nominal steel density of 7,850 kg/m³. These are calculated examples, not Gnee inventory specifications.
Theoretical Weight = Thickness × Width × Length × Density
| Plate Dimensions (mm) | Weight per Plate | Quantity | Total Weight |
|---|---|---|---|
| 10 × 2000 × 6000 | 942 kg | 50 | 47.10 t |
| 12 × 2000 × 6000 | 1,130.4 kg | 50 | 56.52 t |
| 16 × 2000 × 6000 | 1,507.2 kg | 50 | 75.36 t |
| 20 × 2000 × 6000 | 1,884 kg | 50 | 94.20 t |
| 25 × 2000 × 6000 | 2,355 kg | 50 | 117.75 t |
For example, an order consisting of 50 pieces of 16Mo3 pressure vessel steel plate measuring 20 × 2000 × 6000 mm has a theoretical total weight of approximately 94.2 metric tons.
Actual shipment weight may vary depending on dimensional tolerances, cutting requirements and packaging.
