Hastelloy X Wire (UNS N06002, ASTM B572)

Product Introduction

Hastelloy X (UNS N06002, W.Nr. 2.4665, AMS 5754, ASTM B572) is a nickel-chromium-iron-molybdenum solid solution strengthened high-temperature alloy. It is a "weld-friendly" candidate among high-temperature alloys. It does not pursue the maximum strength, but achieves an ultimate balance between oxidation resistance, thermal fatigue resistance and machinability.

For high-temperature components that require welding complex thin-walled structures, such as the combustion chamber flame tubes of aircraft engines and muffle canisters of industrial furnaces, Hastelloy X is an industry standard that has been proven over decades.

Typical applications include:

Aerospace: Gas turbine combustor flame tubes, transition ducts, fuel injectors, flame stabilizers, afterburners, tailpipes

Industrial furnaces: Furnace rollers, muffle cans, catalyst support grids, radiant tubes, heat treatment fixtures

Petrochemicals: Hydrocarbon cracking pipes, flash dryer components, stress corrosion cracking resistant fasteners

Nuclear power: Reactor internals, high-temperature fasteners

Machining and Welding

We typically supply Hastelloy X in solution-treated condition as the standard delivery condition, which is probably one of the easiest to weld among all high-temperature alloys.

1. Welding – No preheating, no post-heat treatment

2. Cold forming – Work hardening similar to austenitic stainless steel

3. Hot working – Above 1177℃, ensuring heat penetration

4. Heat treatment – ​​Solution treatment is key

5. Machining – Annealed state dries easily, spring-tempered state is more costly to machine tools

Standards/Grades

When you're looking for Hastelloy X-cables, you need to confirm that these details match:

ASTM B572 (Core Standard for Bars/Wires)

AMS 5754 (Aerospace Grade Bars/Wires Specification)

AMS 5798 (Aerospace Grade Welding Wire/Fill Metal Specification)

UNS N06002 (Most Common Unified Number)

W.Nr. 2.4665 (German Standard Number)

Technical Consultation Prior to Quotation

We have compiled a summary of key technical parameters regarding Hastelloy X-points frequently discussed during past inquiries and procurement orders-to facilitate rapid quotation.

Diameter: 0.05mm to several millimeters

Condition: Annealed (soft, for customer-made molding/welding) or Tempered spring (high strength, ready to use)

Surface: Bright, pickled

Certification Requirements: Does it come with AMS 5754 certification? Is it for use in aero-engines?

Condition Selection Recommendations:

Requires self-winding of springs or making welded structural components → Annealed (good plasticity, easy to process)

Using pre-made springs and fasteners directly → Tempered spring (strength 200 ksi min)

This is the most common pitfall-the strength difference between annealed and tempered springs is nearly double; be sure to confirm this when purchasing.
