Material Overview

Hastelloy X is a nickel-chromium-iron-molybdenum superalloy renowned for exceptional performance in high-temperature environments. The hot rolled and cold drawn Hastelloy X round bar combines excellent mechanical properties, chemical stability, and processing versatility for reliable performance under extreme heat conditions.

Chemical Composition

Precisely controlled composition ensuring outstanding high-temperature resistance and corrosion resistance:

Nickel (Ni): 47.0% - 50.0% (base element providing excellent ductility and thermal fatigue resistance)
Chromium (Cr): 20.5% - 23.0% (enhances oxidation resistance and high-temperature corrosion resistance)
Iron (Fe): 17.0% - 20.0% (improves strength and processability while maintaining cost-effectiveness)
Molybdenum (Mo): 8.0% - 10.0% (boosts high-temperature strength and resistance to pitting corrosion)
Cobalt (Co): 0.5% - 2.5% (improves high-temperature creep strength and thermal stability)
Tungsten (W): 0.2% - 1.0% (enhances high-temperature strength and hardness)
Carbon (C): Maximum 0.10% (controls carbide formation to avoid brittleness)
Silicon (Si): Maximum 1.0% (assists in deoxidation and improves oxidation resistance)
Manganese (Mn): Maximum 1.0% (enhances workability and toughness)
Phosphorus (P): Maximum 0.04% (prevents brittleness at high temperatures)
Sulfur (S): Maximum 0.03% (minimizes harmful sulfide inclusions)

Mechanical Properties

Optimized mechanical properties through hot rolled and cold drawn processes:

Tensile Strength (σb): Minimum 760 MPa (increases 10-15% after cold drawing)
Yield Strength (σ0.2): Minimum 380 MPa (420-480 MPa after cold drawing)
Elongation (δ5): Minimum 30% (maintains above 20% after cold drawing)
Reduction of Area (ψ): Minimum 40% (excellent toughness and fracture resistance)
Hardness (HB): Hot rolled: 200-240 HB; Cold drawn: 230-280 HB
High-Temperature Performance: 800°C tensile strength above 450 MPa; 1000°C tensile strength around 280 MPa

Key Features

Excellent High-Temperature Resistance

Withstands continuous operating temperatures up to 1200°C and short-term exposure to 1300°C. Resists oxidation, carburization, and nitridation in high-temperature atmospheres.

Superior Mechanical Stability

Refined grain structure with low thermal expansion coefficient and excellent thermal fatigue resistance under cyclic heating and cooling conditions.

Outstanding Corrosion Resistance

Excellent resistance to dilute sulfuric acid, hydrochloric acid, and organic acids in high-temperature and corrosive environments.

Good Processability

Hot rolled bars offer good plasticity for forging and welding; cold drawn bars provide high dimensional accuracy (±0.05 mm) and smooth surface finish (Ra ≤ 1.6 μm).

Long Service Life

Excellent resistance to high-temperature creep, thermal fatigue, and corrosion ensures stable performance in harsh conditions, reducing maintenance frequency.
