IN718 Nickel-Based Superalloy Powder for DED Additive Manufacturing, Laser Metal 3D Printing & High-Temperature Components
Product Overview
GREENSTONE IN718 nickel-based superalloy powder is a high-performance spherical metal powder designed for Directed Energy Deposition (DED), laser metal 3D printing, laser cladding and additive manufacturing of components requiring high mechanical strength, fatigue resistance and reliable performance at elevated temperatures.
IN718 is an internationally recognized precipitation-hardenable nickel-based superalloy widely used for demanding components in aerospace, energy, power generation, industrial manufacturing and high-temperature engineering. Its nickel-chromium matrix, combined with niobium, molybdenum, titanium and aluminum, provides an excellent balance of strength, oxidation resistance, fatigue performance and thermal stability.
The spherical powder morphology provides good flowability and consistent powder feeding, making IN718 particularly suitable for precision DED deposition, component repair, near-net-shape manufacturing and metal additive manufacturing.
High-Strength Nickel-Based Superalloy
IN718 is designed for applications where conventional alloys cannot provide sufficient mechanical performance at elevated temperatures. The alloy retains high strength and good structural stability under demanding thermal and mechanical loading conditions.
Optimized for DED & Metal Additive Manufacturing
GREENSTONE IN718 powder features a spherical morphology suitable for stable powder delivery and controlled deposition. It can be used in powder-fed DED systems, laser metal deposition, laser cladding and compatible metal 3D printing processes.
Controlled powder morphology helps provide:
- Stable powder feeding and good flowability
- Consistent melt-pool material delivery
- Uniform deposited layers
- Reduced process fluctuations
- Reliable performance during multi-layer additive manufacturing
Excellent High-Temperature Performance
IN718 is widely selected for components operating under combined high-temperature and mechanical loads. Its precipitation-hardening characteristics provide excellent strength after appropriate heat treatment while maintaining good fatigue and creep resistance.
This makes the material particularly suitable for turbine-related components, high-temperature structural parts, energy equipment and other thermally loaded industrial components.
Strong Mechanical & Fatigue Properties
The alloy provides an excellent combination of tensile strength, fatigue resistance and toughness. These characteristics are especially important for DED-manufactured and repaired components exposed to cyclic loading, vibration and demanding service environments.
Good Oxidation & Corrosion Resistance
The high nickel and chromium content provides good resistance to oxidation and corrosion, allowing IN718 components and deposited layers to perform reliably in demanding industrial environments.
Spherical Gas-Atomized Powder
Gas atomization produces highly spherical particles with controlled particle size distribution, supporting consistent powder flow and repeatable processing. Particle size ranges can be selected according to the deposition system and application.
A typical range for additive manufacturing is 15–45 μm, while other particle size distributions can be supplied for DED and laser cladding applications.
