Bright and Black Surface Hastelloy X Round Bar / Nickel Alloy Bars
Hastelloy X Rod In Custom Length
Product Overview
Hastelloy X is a nickel-chromium-iron-molybdenum alloy designed to
exhibit exceptional oxidation resistance and high mechanical
strength at elevated temperatures up to 1200°C -1. Our Bright and Black Surface Hastelloy X round bars are
precision-engineered to meet the stringent demands of industries
operating in extreme environments. These bars offer a unique
combination of excellent fabricability, outstanding resistance to
thermal fatigue, and good ductility for forming and welding
operations.
We supply these high-performance nickel alloy bars in both Bright
Polished and Black surfaces, with the capability to provide them in
custom lengths tailored to your specific project requirements.
Whether you are constructing industrial furnaces, aerospace engine
components, or chemical processing equipment, our Hastelloy X round
bars deliver unmatched performance and reliability.
Chemical Composition
The superior properties of Hastelloy X are derived from its
carefully balanced chemical composition, which promotes exceptional

Key Features & Advantages
Exceptional High-Temperature Performance: Demonstrates excellent
oxidation resistance up to 1200°C and maintains moderate creep and
stress-rupture strength above 790°C, making it suitable for the
hottest sections of industrial equipment .
Superior Corrosion Resistance: Offers excellent resistance to a
variety of corrosive environments, including reducing atmospheres,
and exhibits good resistance to stress corrosion cracking .
Excellent Fabricability: Possesses good cold and hot workability
and can be welded by conventional methods like argon arc welding,
seam welding, and spot welding, allowing for great flexibility in
manufacturing complex components .
Versatile Material Supply: Our round bars are available in
hot-rolled, cold-drawn, forged, and solution-annealed states,
ensuring you get the right material condition for your application
.
Typical Applications
Hastelloy X round bars are widely used in demanding sectors across
multiple industries:
Aerospace & Aviation: Ideal for jet engine combustion chambers,
afterburners, flame holders, turbine casings, and other
high-temperature structural components .
Industrial Heating & Processing: Used for furnace components such
as radiant tubes, rolls, muffles, burner nozzles, and heat
treatment fixtures .
Power Generation: Applied in gas turbine combustion liners,
transition ducts, and components for high-temperature gas-cooled
nuclear reactors .
Chemical Processing: Suitable for parts exposed to high
temperatures and corrosive atmospheres, such as reactor internals
and heat exchanger tubing in petrochemical furnaces .
Quality Assurance & Packaging
Our production of Hastelloy X round bars complies with
international standards such as ASTM B572 for bar and AMS 5754 for
forging . We employ rigorous quality control procedures throughout
the manufacturing process. Each batch is accompanied by a Mill Test
Certificate (MTC) to guarantee compliance with chemical and
mechanical property specifications.
The bars are securely packaged using waterproofed bags or
standardized wooden cases to prevent damage during transit and
storage .
