LayrrNickel 718 - Inconel 718

Product Intelligence

If there is one alloy that enabled the modern era of additive manufacturing in aerospace, it is Inconel 718. But its ubiquity makes consistency even more critical.

Layrr Materials Inconel® 718 is engineered for the "mission-critical." While standard 718 is available everywhere, we supply a powder specifically atomized to minimize satellite formation and porosity. We understand that in high-stakes environments—like rocket combustion chambers—material reliability is the only metric that matters. Our powder offers the precise chemistry required to achieve full mechanical properties after heat treatment.

Material Behavior & Microstructure

Inconel 718 is a precipitation-hardenable nickel-chromium alloy, distinct from solid-solution alloys (like 625) due to the addition of Niobium.

This addition creates the strengthening that precipitates during aging, delivering:

1. High-Temperature Strength: Exceptional tensile, fatigue, and creep-rupture strength at temperatures up to 700°C (1290°F).

2. Weldability: Unlike many superalloys, 718 is resistant to strain-age cracking. This sluggish hardening response is exactly what makes it the most "printable" superalloy on the market.

3. Cryogenic Stability: Maintains ductility in freezing environments, making it ideal for liquid fuel systems.

Processing Advantage: The Layrr Standard

We supply 718 in cuts optimised for LPBF (15-45µm) and EBM/DED (45-105µm).

• Satellite-Free Morphology: High sphericity ensures the powder flows like a liquid during recoating, preventing short-feeds and layer defects.
• Low Oxide Content: Oxygen pickup is the enemy of superalloys. Our vacuum-sealed handling ensures you start with a clean feedstock, maximizing powder reuse cycles.

• Consistent Apparent Density: Vital for repeatable volumetric dosing in automated systems.

Critical Applications

From jet engines to static land-based turbines, Inconel 718 is the default choice for hot-section components:

• Aerospace Propulsion: Liquid rocket engine injectors, combustion liners, and high-pressure turbopumps.
• Gas Turbines: Blades, vanes, and casings requiring creep resistance.
• Oil & Gas: Downhole tools and wellhead components subjected to high pressure and corrosive sour gas.
• Nuclear: High-strength structural springs and fasteners.
