Hastelloy Alloys: Material Overview
Hastelloy alloys represent a family of high-performance nickel-based superalloys renowned for their exceptional resistance to corrosion, high-temperature strength, and durability in demanding industrial environments. Our round bar product line includes Hastelloy C276, Hastelloy B-2, Hastelloy B-3, and Hastelloy X—each engineered with unique chemical compositions to excel in specific applications.
Hastelloy C276 Round Bars
Hastelloy C276 is a nickel-chromium-molybdenum alloy with unmatched resistance to a broad spectrum of corrosive media. Its composition includes 54-60% nickel, 14-18% chromium, 15-17% molybdenum, 3-4.5% tungsten, and ≤2% iron.
- Corrosion Resistance: Withstands oxidizing and reducing environments including sulfuric acid, hydrochloric acid, chlorine gas, and seawater
- Mechanical Strength: Minimum tensile strength of 100 ksi/689 MPa and yield strength of 45 ksi/310 MPa at room temperature
- Fabricability: Easily machined, welded, and formed with specialized tooling
Hastelloy B-2 Round Bars
Hastelloy B-2 is optimized for resistance to strongly reducing environments, particularly those containing hydrochloric acid, with 65-70% nickel and 26-30% molybdenum composition.
- Reducing Environment Resistance: Excels in pure hydrochloric acid and other reducing acids
- Thermal Stability: Maintains properties at temperatures up to 1800°F (982°C)
- Mechanical Performance: Minimum tensile strength of 95 ksi (655 MPa) and yield strength of 40 ksi (276 MPa)
Hastelloy B-3 Round Bars
Hastelloy B-3 offers improved resistance to pitting, crevice corrosion, and stress corrosion cracking in mixed acid environments with refined composition including 65-70% nickel and 27-32% molybdenum.
- Mixed Environment Resistance: Outperforms B-2 in solutions containing both reducing acids and oxidizing contaminants
- Weldability: Superior post-weld corrosion resistance without need for heat treatment
- Mechanical Toughness: Minimum tensile strength of 100 ksi (689 MPa) with excellent ductility
Hastelloy X Round Bars
Hastelloy X is engineered for high-temperature strength and oxidation resistance with balanced composition including 47-54% nickel, 18-22% chromium, 17-20% iron, and 8-10% molybdenum.
- High-Temperature Performance: Maintains structural integrity at temperatures up to 2200°F (1204°C)
- Thermal Fatigue Resistance: Withstands repeated thermal cycling without cracking
- Fabricability: Easily welded, forged, and machined with good formability at elevated temperatures
Manufacturing Processes: Cold Drawn vs. Hot Rolled
Cold Drawn Hastelloy Round Bars
Cold drawing involves pulling bars through a die at room temperature, refining grain structure and improving surface quality.
- Precision dimensional tolerances with tight diameter control
- Superior smooth, polished surface finish (1.6-6.3 μm Ra)
- Enhanced mechanical properties with 10-20% increased tensile strength
- Grain refinement for improved toughness and corrosion resistance
Hot Rolled Hastelloy Round Bars
Hot rolling involves heating above recrystallization point and shaping through rolls, then cooling to room temperature.
- Cost-effective production for large-diameter bars
- Improved ductility and formability for easier fabrication
- Large size range from 0.5 inches to 24+ inches diameter
- Minimized internal stresses reducing warping or cracking risk
