Hot Rolled and Cold Drawn Hastelloy X Round Bar for High-Temperature Applications
Hastelloy X is a nickel - chromium - iron - molybdenum superalloy renowned for its exceptional performance in high - temperature environments. The hot rolled and cold drawn Hastelloy X round bar, as a high - precision product derived from this superior alloy, combines excellent mechanical properties, chemical stability, and processing versatility, making it an indispensable material in industries that demand reliable performance under extreme heat conditions.
1. Chemical Composition
The chemical composition of Hastelloy X round bar is precisely controlled to ensure its outstanding high - temperature resistance and corrosion resistance. The typical composition (by weight percentage) is as follows:
- Nickel (Ni): 47.0% - 50.0% (serves as the base element, providing excellent ductility and resistance to thermal fatigue)
- Chromium (Cr): 20.5% - 23.0% (enhances oxidation resistance and high - temperature corrosion resistance, forming a dense oxide film on the surface)
- Iron (Fe): 17.0% - 20.0% (improves the alloy's strength and processability while maintaining cost - effectiveness)
- Molybdenum (Mo): 8.0% - 10.0% (boosts the alloy's strength at high temperatures and enhances resistance to pitting and crevice corrosion)
- Cobalt (Co): 0.5% - 2.5% (aids in improving the alloy's high - temperature creep strength and thermal stability)
- Tungsten (W): 0.2% - 1.0% (further enhances the alloy's high - temperature strength and hardness)
- Carbon (C): Maximum 0.10% (controls the formation of carbides to avoid brittleness while maintaining appropriate strength)
- Silicon (Si): Maximum 1.0% (assists in deoxidation during the manufacturing process and improves oxidation resistance)
- Manganese (Mn): Maximum 1.0% (enhances the alloy's workability and toughness)
- Phosphorus (P): Maximum 0.04% (strictly controlled to prevent brittleness at high temperatures)
- Sulfur (S): Maximum 0.03% (minimized to avoid the formation of harmful sulfide inclusions)
2. Mechanical Properties
The hot rolled and cold drawn processes significantly optimize the mechanical properties of Hastelloy X round bar, enabling it to maintain excellent performance even in high - temperature environments. The typical mechanical properties (tested at room temperature unless otherwise specified) are listed below:
- Tensile Strength (σb): Minimum 760 MPa (after cold drawing, the tensile strength can be further increased by 10% - 15% compared to the hot rolled state, depending on the degree of cold working)
- Yield Strength (σ0.2): Minimum 380 MPa (the cold drawn round bar has a higher yield strength, usually ranging from 420 MPa to 480 MPa, ensuring better resistance to plastic deformation under load)
- Elongation (δ5): Minimum 30% (even after cold drawing, the elongation remains above 20%, maintaining good ductility for forming and processing)
- Reduction of Area (ψ): Minimum 40% (indicates excellent toughness and resistance to fracture during stress application)
- Hardness (HB): Hot rolled state: 200 - 240 HB; Cold drawn state: 230 - 280 HB (the increase in hardness after cold drawing enhances the wear resistance of the round bar, making it suitable for applications with slight wear conditions)
- High - temperature Mechanical Properties: At 800°C, the tensile strength is still above 450 MPa, and the creep rupture strength (1000 hours) is about 180 MPa; at 1000°C, the tensile strength is around 280 MPa, and the creep rupture strength (1000 hours) is approximately 80 MPa. These properties ensure the round bar can operate stably for a long time in high - temperature working conditions.
3. Key Features
3.1 Excellent High - temperature Resistance
Hastelloy X round bar can withstand continuous operating temperatures up to 1200°C and short - term exposure temperatures up to 1300°C. Its unique alloy composition enables it to resist oxidation, carburization, and nitridation in high - temperature atmospheres, avoiding performance degradation caused by high - temperature corrosion.
3.2 Superior Mechanical Stability
The combination of hot rolling and cold drawing processes refines the grain structure of the alloy, reducing internal defects and improving the uniformity of mechanical properties. Even under cyclic heating and cooling conditions (thermal cycling), the round bar has low thermal expansion coefficient and good thermal fatigue resistance, minimizing the risk of cracking or deformation.
3.3 Outstanding Corrosion Resistance
In addition to high - temperature corrosion resistance, Hastelloy X round bar also exhibits excellent resistance to various corrosive media, such as dilute sulfuric acid, hydrochloric acid (at low concentrations and moderate temperatures), and organic acids. This makes it suitable for applications where high - temperature and corrosive environments coexist.
3.4 Good Processability
The hot rolled round bar has good plasticity, which is easy for forging, bending, and welding; the cold drawn round bar has high dimensional accuracy (tolerance can be controlled within ±0.05 mm) and smooth surface finish (Ra ≤ 1.6 μm), reducing the need for subsequent processing and improving production efficiency.
3.5 Long - term Service Life
Due to its excellent resistance to high - temperature creep, thermal fatigue, and corrosion, the Hastelloy X round bar can maintain stable performance for a long time in harsh working conditions, reducing the frequency of equipment maintenance and replacement and lowering the overall operating cost.
4. Applications
Owing to its comprehensive performance advantages, the hot rolled and cold drawn Hastelloy X round bar is widely used in various high - temperature industries, including but not limited to:
4.1 Aerospace Industry
- Manufacture of high - temperature components in aircraft engines, such as turbine blades, turbine disks, combustion chambers, and afterburners. These components need to withstand high temperatures (up to 1100°C) and high - speed rotation loads, and the Hastelloy X round bar's excellent high - temperature strength and creep resistance can meet these strict requirements.
- Production of structural parts for rocket engines and space shuttles, which are exposed to extreme high - temperature environments during launch and re - entry, and the round bar's thermal stability and corrosion resistance ensure the safety and reliability of the equipment.
4.2 Energy Industry
- Used in the manufacturing of high - temperature components for gas turbines (such as rotor shafts, stator blades, and combustion chambers) in power plants. Gas turbines operate at high temperatures (800 - 1000°C) and high pressures, and the Hastelloy X round bar's mechanical properties and corrosion resistance can ensure the long - term stable operation of the turbine.
- Application in the nuclear power industry, such as the manufacture of heat exchanger tubes and structural parts in nuclear reactors. The round bar's resistance to radiation - induced embrittlement and corrosion in high - temperature coolant (such as water or liquid metal) makes it a safe and reliable material choice.
4.3 Petrochemical Industry
- Production of high - temperature and high - pressure valves, fittings, and pipelines for petrochemical plants. These components are in contact with corrosive media (such as crude oil, natural gas, and chemical solvents) at high temperatures (300 - 800°C), and the Hastelloy X round bar's corrosion resistance and high - temperature strength can prevent leakage and failure of the components.
- Manufacture of catalyst supports and reactor internals in the chemical synthesis process. The round bar's chemical stability ensures that it does not react with the catalyst or the reactants, maintaining the efficiency and purity of the chemical reaction.
4.4 Other High - temperature Applications
- Used in the manufacturing of heating elements, furnace linings, and structural parts for high - temperature furnaces (such as industrial heating furnaces and laboratory high - temperature test furnaces). The round bar's high - temperature resistance and oxidation resistance can withstand the long - term high - temperature environment inside the furnace.
- Application in the automotive industry for the manufacture of high - performance exhaust system components (such as exhaust manifolds and tailpipes) for high - performance cars and racing cars. These components need to withstand high temperatures (up to 900°C) and vibration loads, and the round bar's thermal fatigue resistance and mechanical strength can meet these needs.
