IMT IN718 superalloy metal powder 15–53 µm, 5 kg

IMT IN718 15–53 µm: Heat-resistant nickel superalloy powder for extreme conditions

IMT IN718 is a metallic nickel-chromium superalloy powder (Inconel 718), designed for 3D printing using SLM/LPBF technology. The material is distinguished by exceptional tensile strength, fatigue and corrosion resistance, and most importantly, the ability to maintain its mechanical properties at temperatures up to 700°C.

This powder series is produced by the EIGA method (Electrode Induction Inert Gas Atomization). Unlike the standard VIGA method, the EIGA technology eliminates the contact of molten metal with the crucible. This prevents material contamination by lining and reduces reaction time with residual gases, allowing for a product with minimal oxygen, nitrogen, and hydrogen content.

Powder fraction 15–53 µm has high sphericity (≥ 90%) and excellent flowability (≤ 15 s/50g), ensuring layer uniformity and printing stability.

Packaging: hermetic container 5 kg.

Technical profile of the material

Chemical composition

The alloy has a complex multi-component structure where nickel and iron form a strong matrix, reinforced by niobium and molybdenum:

• Nickel (Ni): 52.0% — the base that provides heat resistance and corrosion resistance.
• Chromium (Cr): 18.5% — increases oxidation resistance at high temperatures.
• Niobium (Nb): 5.1% — the main element for dispersion hardening.
• Molybdenum (Mo): 3.0% — enhances matrix hardness.
• Titanium (Ti): 0.9% and Aluminum (Al): 0.5%.
• Iron (Fe): base (Balance).
• Impurities: O (≤150 ppm), N (≤100 ppm), C (≤0.08%), Si (≤0.35%), Mn (≤0.35%).

Physical properties of the powder

The EIGA method ensures high purity and morphological perfection of particles:

• Sphericity: ≥ 90%.
• Flowability (Hall flow): ≤ 15 s/50g.
• Apparent density: ≥ 4.3 g/cm³.

Mechanical properties at different temperatures

The material demonstrates high endurance even under extreme heating:

• At normal temperature: tensile strength 1320–1380 MPa; yield strength 1070–1140 MPa; elongation ≥ 26%.
• At 650°C: tensile strength 1060–1110 MPa; yield strength 920–980 MPa.
• At 1000°C: retains strength 121–141 MPa.
• Long-term strength (650°C, 690 MPa): time to rupture ≥ 40 hours.

Advantages of the EIGA production method

The use of crucible-free induction melting provides critical advantages for responsible industries:

• Maximum purity: no contact with crucible ceramics eliminates the inclusion of non-metallic inclusions.
• Low gas saturation: minimal oxygen and nitrogen content improves material viscosity and fatigue.
• Stability of characteristics: batch production guarantees repeatability of results from batch to batch.

Applications and examples of parts

Superalloy IN718 is the industry standard for aerospace and energy sectors:

• Aerospace: turbine blades and disks, combustion chamber elements, engine casings.
• Rocket technology: components of liquid rocket engines, fasteners operating at cryogenic and high temperatures.
• Energy: gas turbine parts and heat exchange equipment.
• Oil and gas industry: tools for deep-sea drilling resistant to corrosion cracking.
