Product Description
10CrMo9-10 Low Alloyed Steel Boiler Tubes
10CrMo9-10 is a low-alloy heat-resistant steel widely used in high-temperature, high-pressure applications such as boilers, pressure vessels, and power plant piping. Its properties come mainly from its chromium (Cr) and molybdenum (Mo) content, which improve strength and creep resistance at elevated temperatures.
Chemical Composition
Element Weight %
Carbon (C) 0.08 – 0.15%
Silicon (Si) ≤ 0.50%
Manganese (Mn) 0.40 – 0.90%
Phosphorus (P) ≤ 0.025%
Sulfur (S) ≤ 0.010%
Chromium (Cr) 2.00 – 2.50%
Molybdenum (Mo) 0.90 – 1.10%
Nickel (Ni) ≤ 0.30% (residual)
Copper (Cu) ≤ 0.30% (residual)
Nitrogen (N) ≤ 0.012% (if specified)
Iron (Fe) Balance
Key Element Functions
  • Chromium (around 2–2.5%) - Improves oxidation and corrosion resistance at high temperatures. Increases hardenability and strength.
  • Molybdenum (around 1%) - Significantly improves high-temperature strength and creep resistance. Enhances resistance to softening at elevated temperatures.
  • Low carbon (0.08–0.15%) - Balances strength with weldability. Helps avoid excessive hardness and cracking in the heat-affected zone when welding.
  • Controlled P and S (very low) - Better toughness and reduced risk of hot cracking.
Standards and Designations
  • European grade designation: 10CrMo9-10
  • EN standard: Typically EN 10028-2 (pressure vessel plates) and EN 10216-2 / EN 10217-2 (seamless/welded tubes for elevated temperatures)
  • Similar grades: Comparable to ASTM A335 P22 or 13CrMo4-5 family steels (not direct substitutes)
Important Note: Exact limits can vary depending on product form, standard edition, and manufacturer. For design, fabrication, or certification, always check the relevant material standard and confirm with the mill test certificate (MTC) from the supplier.
