As a trusted Hastelloy X Pipe Fittings Manufacturer, Exporter, and Supplier, we provide premium-quality alloy fittings that perform exceptionally in extreme environments. Our Hastelloy X fittings are engineered to deliver strength, durability, and corrosion resistance in high-temperature and oxidizing conditions — making them ideal for aerospace, chemical, and petrochemical applications.
Hastelloy X, a nickel-based superalloy, is widely known for its outstanding resistance to oxidation and high-temperature creep. When fabricated into pipe fittings, this alloy ensures leak-proof, long-lasting performance in demanding fluid handling systems. Choosing a reliable manufacturer and exporter guarantees that every fitting meets international quality standards and project specifications.
What is Hastelloy X?
Hastelloy X (UNS N06002) is a nickel-chromium-iron-molybdenum alloy designed to withstand high-temperature oxidation and stress-corrosion cracking. With superior mechanical strength and excellent formability, it is one of the most versatile heat-resistant alloys in industrial use.
Chemical Composition
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 47.5 |
| Chromium (Cr) | 22.0 |
| Iron (Fe) | 18.5 |
| Molybdenum (Mo) | 9.0 |
| Others | Balance |
This balanced composition provides exceptional resistance to oxidation up to 1200 °C and maintains strength under cyclic heating conditions. Hastelloy X conforms to ASTM B366 and ASME SB366 standards for buttweld fittings.
Types of Hastelloy X Pipe Fittings
We manufacture and export a complete range of Hastelloy X Buttweld Pipe Fittings that conform to ASME B16.9 and MSS-SP-43 standards. Each type serves a distinct purpose in pipeline systems:
- Elbows (90°, 45°) – Change pipe direction while maintaining smooth flow.
- Tees – Allow branching of pipelines for multiple flow paths.
- Reducers (Concentric / Eccentric) – Connect pipes of differing diameters.
- Cross Fittings – Facilitate four-way connections in process systems.
- Caps & Stub Ends – Used to terminate or connect piping sections.
- Couplings & Unions – Join two pipes securely for easy maintenance.
Our Nickel Alloy Hastelloy X Fittings are available in seamless, welded, and fabricated forms to meet varied project needs.
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | 785 MPa (min) |
| Yield Strength | 355 MPa (min) |
| Elongation | 45 % |
| Density | 8.22 g/cm³ |
| Hardness | 85 HRB |
These properties make Hastelloy X fittings suitable for high-stress and high-temperature applications.
