13CrMo4-5 is a low-alloy heat-resistant steel widely used in pressure vessels, boilers, and high-temperature piping systems, particularly in power plants and petrochemical facilities. Its chemical composition is standardized in EN 10028-2 and EN 10216-2.
Chemical Composition
Element
Content (Weight %)
Carbon (C)
0.10 – 0.18
Silicon (Si)
≤ 0.35
Manganese (Mn)
0.40 – 0.70
Phosphorus (P)
≤ 0.025
Sulfur (S)
≤ 0.010
Chromium (Cr)
0.70 – 1.15
Molybdenum (Mo)
0.40 – 0.60
Nitrogen (N)
≤ 0.012
Copper (Cu)
≤ 0.30
Nickel (Ni)
≤ 0.30
Composition Benefits
Chromium (approx. 1%): Enhances oxidation and corrosion resistance at elevated temperatures while maintaining strength and microstructural stability during long-term service
Medium Carbon and Manganese: Provides optimal balance of strength, toughness, and weldability
Low Phosphorus and Sulfur: Controlled levels improve toughness and reduce risks of hot cracking and embrittlement
Typical Applications
Boiler drums, headers, and steam lines
High-temperature pressure vessels
Superheater and reheater tubes
Power plant and refinery components operating at 450–550°C
Important Note: For design, material selection, or welding procedure qualification, always refer to the actual standards (EN 10028-2, EN 10216-2) or mill test certificates for exact specified limits and measured composition values.
