Chemical Composition (Weight %)
Element Composition Range
Carbon (C) 0.15 max
Manganese (Mn) 0.30 - 0.60
Phosphorus (P) 0.025 max
Sulfur (S) 0.025 max
Silicon (Si) 0.25 - 1.00
Chromium (Cr) 8.00 - 10.00
Molybdenum (Mo) 0.90 - 1.10
Nickel (Ni) 0.40 max (optional)
Vanadium (V) 0.18 max (optional)
Iron (Fe) Balance
The 9% Cr-1% Mo composition provides exceptional high-temperature strength and oxidation resistance, while low carbon content ensures good weldability.
Mechanical Properties
Property Value
Tensile Strength (min) 415 MPa (60,000 psi)
Yield Strength (min) 205 MPa (30,000 psi)
Elongation (min, % in 50mm) 30%
Hardness (max, Brinell HBW) 179 HBW
Impact Toughness (Charpy V-Notch, min at 21°C) Typically required (varies by spec)
Supplied in normalized & tempered condition for optimal strength and ductility. Retains strength up to ~650°C (1200°F) and requires preheating (~200-300°C) with post-weld heat treatment (PWHT) to prevent cracking.
Studded Finned Tube Design Advantages
  • Increased Surface Area: Studs significantly enhance heat transfer surface for superior thermal efficiency
  • Compact Design: Maximizes heat transfer capacity without increasing physical footprint
  • High-Temperature Performance: Resilient in extreme conditions up to 650°C (1200°F)
  • Reduced Fouling: Smooth stud surfaces minimize deposit buildup compared to traditional fins
  • Enhanced Durability: Superior erosion/corrosion resistance in harsh industrial environments
Industrial Applications
  • Power Generation: Heat Recovery Steam Generators (HRSGs), Fluidized Bed Boilers, Superheaters
  • Petrochemical: Fired Heaters, Catalytic Cracking Units (FCCU), Coker Units
  • Waste Treatment: Waste-to-Energy Plants, Air Preheaters (APH)
  • Chemical Processing: Sulfuric Acid Plants, Ammonia Production, Syngas Coolers
  • Heavy Industry: Cement Clinker Coolers, Blast Furnace Gas Ducts
