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
