EN10028-2 13CrMo4-5 steel plate is a type of pressure vessel steel designated by the European standard EN10028, specifically designed for applications in boilers and pressure vessels. This grade is widely recognized for its excellent mechanical properties and resistance to high-temperature environments, making it suitable for critical applications in the power generation and petrochemical industries.

Chemical Composition:

The chemical composition of 13CrMo4-5 is carefully controlled to ensure the necessary balance of strength, toughness, and corrosion resistance. The typical chemical composition is as follows:

· Carbon (C): 0.10 - 0.18%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): 0.40 - 0.90%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.010%

· Chromium (Cr): 0.80 - 1.20%

· Molybdenum (Mo): 0.45 - 0.65%

Mechanical Properties:

The mechanical properties of 13CrMo4-5 steel plate are characterized by its high strength and excellent resistance to creep at elevated temperatures. The typical mechanical properties include:

· Yield Strength: ≥ 275 MPa

· Tensile Strength: 480 - 630 MPa

· Elongation: ≥ 20%

· Impact Energy (Charpy V-notch test at room temperature): ≥ 40 J

Heat Treatment:

The steel is generally supplied in a normalized and tempered condition. This heat treatment process ensures that the material has a uniform microstructure and optimal mechanical properties. The normalization process involves heating the steel to a temperature above its critical point and then cooling it in air. Tempering follows, which is a heat treatment process applied to increase toughness and ductility after hardening.

Available Dimensions:

TJC Steel Group offers 13CrMo4-5 steel plates in a wide range of sizes to meet the diverse needs of its customers. The available dimensions typically include:

· Thickness: 6mm - 300mm

· Width: 1500mm - 4020mm

· Length: 3000mm - 18000mm

Low-Temperature Impact Test:

13CrMo4-5 steel plates are also available with a low-temperature impact test, ensuring that the material maintains its toughness and impact resistance at sub-zero temperatures. This is particularly important for applications in cold environments or where the equipment may be exposed to low temperatures.

Main Applications:

The primary applications for 13CrMo4-5 steel plates include:

· Boilers and superheaters

· Heat exchangers

· Pressure vessels

· Steam lines

· Petrochemical equipment
