Corrosion-Resistant Hastelloy X Round Bar for Aerospace Applications with High-Temperature Strength

Hastelloy X (UNS N06002) is a nickel-chromium-iron-molybdenum alloy specifically engineered for exceptional performance in high-temperature and severely corrosive environments. This solid-solution strengthened superalloy is particularly valued in aerospace and heat exchanger applications where excellent oxidation resistance and reliable structural integrity are required. Our precision-manufactured Hastelloy X round bars undergo stringent quality control to ensure consistent performance in critical applications such as combustion chambers, transition ducts, and heat exchanger components.

The chemical composition of Hastelloy X is carefully balanced to provide optimal high-temperature properties and corrosion resistance. The table below details the elemental composition range per international standards.

Hastelloy X round bars maintain excellent mechanical properties across a wide temperature range, making them suitable for both ambient and high-temperature applications.

The alloy retains significant strength at elevated temperatures, with excellent creep and stress-rupture properties above 790°C (1450°F). This makes it suitable for prolonged service at temperatures up to 900°C, with short-term exposure capabilities up to 1200°C.

• Exceptional High-Temperature Strength: The alloy maintains excellent creep and stress-rupture properties at temperatures above 790°C (1450°F), making it ideal for components under sustained mechanical loads in high-temperature environments.
• Superior Oxidation Resistance: With a chromium content exceeding 20%, Hastelloy X demonstrates outstanding oxidation resistance up to 1200°C. It performs reliably in both oxidizing and reducing atmospheres, preventing rapid degradation.
• Excellent Resistance to Corrosive Environments: The nickel-chromium-molybdenum base provides strong resistance to various corrosive attacks, including sulfidation, carburization, and halogen-containing atmospheres. This is particularly valuable in aerospace and heat exchanger applications where corrosive environments are common.
• Good Fabricability: Hastelloy X offers good formability and weldability compared to many precipitation-hardened superalloys. It can be welded using common techniques such as TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding without requiring post-weld heat treatment in most applications.
• Stable Microstructure: In the solution-annealed condition, the alloy's austenitic matrix with minimal secondary phases ensures long-term stability and performance at high temperatures.

Hastelloy X round bars are produced to meet various international standards, ensuring material quality and consistency.

To support comprehensive manufacturing and repair projects across various industries, Hastelloy X is available in multiple forms:

• Sheets and Plates
• Pipes and Tubes (seamless and welded)
• Fittings and Flanges
• Forged Components (rings, discs, custom shapes)
• Welding Consumables (wire, electrodes)
• 3D Printing Spherical Powder

To ensure our products reach you in perfect condition, we employ rigorous packaging and handling protocols:

• Protective Coating: Round bars are typically coated with a rust-preventive oil to protect against moisture during transit and storage.
• Individual Wrapping: Each bar is individually wrapped in waterproof and anti-corrosive paper or plastic.
• Sturdy Securement: Bundled and securely strapped to wooden or metal pallets to prevent movement and damage during transportation.
• Clear Labeling: All packages are clearly labeled with material grade, heat number, size, and other relevant identification for easy traceability and handling.
• Documentation: Each shipment includes complete documentation, including Material Test Certificates (MTC/CMTR) that certify compliance with the ordered specification, along with heat numbers for traceability.
