Hastelloy X

Used in high temperature & corrosive atmosphere applications. Commonly used in gas turbines, energy generation applications such as transition duct, combustor cans, afterburners, & spray bars.

Material & Process Capability

HASTELLOY® X alloy (UNS N06002) is a nickel-chromium-iron-molybdenum solution strengthened alloy widely used in high temperature and corrosive atmosphere applications. The alloy is commonly used in gas turbine engines. Its corrosion resistance also make it an excellent candidate for applications in petrochemical and energy generation applications, such as transition duct, combustor cans, afterburners, and spray bars.

The Velo3D intelligent additive printing solution uniquely enables companies to build the parts they need without compromising design or quality – resulting in complex, higher performance parts than traditional casting techniques or other additive methods.

General Process

HASTELLOY X possesses excellent forming and welding characteristics and is easy to fabricate. It offers outstanding localized corrosion resistance and oxidation resistance up to 2200°F (1200°C) along with excellent stress corrosion crack resistance.

This data sheet specifies the expected mechanical properties and characteristics of this alloy when manufactured on a Velo3D Sapphire® System. All data is based on parts built using Velo3D standard 50 μm layer thickness parameters, using Praxair TruForm HXLC, a Velo3D-approved HASTELLOY X powder.
