This document specifies handling and storage constraints for Atomfair IN939 SLM superalloy powder. The material is highly sensitive to ambient exposure and must be kept under inert atmosphere to prevent phase contamination.
- Ambient Exposure Sensitivity: Exposure to ambient moisture or oxygen can cause phase contamination or degradation of the powder before thermal validation.
- Inert Gas Handling: When the container is open, handle the powder exclusively within an anhydrous inert gas environment.
- Storage Container: Store the powder in sealed, argon-filled, moisture-proof containers to maintain material integrity.
What particle size distribution and flow properties are specified for Atomfair IN939 SLM superalloy powder?
The technical specification lists a D50 of 30–40 μm, D10 ≥15 μm, and D90 ≤60 μm. Sphericity is ≥0.9, flowability is ≤18 s/50g, apparent density is ≥4.4 g/cm³, and tap density is ≥5.0 g/cm³.
Is Atomfair IN939 superalloy powder suitable for selective laser melting of gas turbine parts?
Yes. The powder is described as an optimized engineered matrix for SLM, and its application scope covers manufacturing gas turbine engine parts in aviation, aerospace, energy, and chemical industries. It is processed under ISO 9001 compliance, and heat-treated properties include tensile strength ≥1200 MPa, yield strength ≥1000 MPa, and elongation ≥7.0% at 25°C; at 600°C the values are ≥1000 MPa, ≥900 MPa, and ≥8.0%.
How should Atomfair IN939 SLM powder be stored and handled to prevent contamination?
Keep the container tightly sealed because the powder is highly sensitive to ambient exposure, and handle it only in an anhydrous inert gas environment to avoid phase contamination or degradation before thermal validation. Standard packaging is sealed argon-filled moisture-proof containers, with customized batch weights available on request.
Atomfair IN939 SLM superalloy powder exhibits high sphericity (≥0.9) and flowability (≤18 s/50g) for reliable SLM processing, with tensile strength ≥1000 MPa at 600°C, but requires strict inert atmosphere handling to prevent ambient degradation.
Positive
- High sphericity and flowability: Sphericity ≥0.9 and flowability ≤18 s/50g ensure consistent powder bed packing and smooth layer spreading in SLM systems, reducing defect formation.
- Excellent high-temperature strength: Heat-treated tensile strength ≥1000 MPa at 600°C with yield strength ≥900 MPa, making it suitable for gas turbine components under thermal stress.
Trade-offs
- Ambient exposure sensitivity: Powder must be stored in sealed argon-filled containers and handled in anhydrous inert gas to prevent oxidation or phase contamination, requiring dedicated inert atmosphere infrastructure.
- Optimized exclusively for SLM: The powder is engineered specifically for selective laser melting; its particle size distribution and morphology may not be suitable for other additive manufacturing or powder metallurgy processes.
