Final price, availability, lead time, chemistry, performance data, and documentation are confirmed for the quoted specification and lot.
Alloy identification
Specify this powder by grade, then narrow the buying requirement.
IN718, Alloy 718, and UNS N07718 are common international designations. Pair GH4169 with the governing chemistry, and state any branded-material requirement explicitly.
Similar grade names do not establish identical chemistry or process compatibility. Include the governing specification and required edition; the quotation confirms the proposed powder and supporting lot records.
Specification controls
Define the powder beyond the alloy designation.
The same grade name can represent materially different powder routes. A usable RFQ needs the acceptance method, limits, packaging, and intended process.
Chemistry & standard
State the governing grade, revision, restricted elements, and any tighter oxygen or nitrogen limits.
PSD & method
Choose a candidate range and state whether sieve, laser diffraction, or a customer method controls acceptance.
Powder behavior
Define required flow, apparent/tap density, morphology evidence, satellites, and hollow-particle limits where relevant.
Lot & reuse plan
Confirm lot size, virgin/reused powder policy, blend restrictions, sampling, retention, and traceability expectations.
Process and PSD
Process and PSD options to confirm in the RFQ.
PSD labels below are catalog starting points. Final fit depends on the machine, layer strategy, feed system, qualification plan, and the supplier lot.
| Decision variable | Catalog starting points | Required confirmation |
|---|---|---|
| Process candidates | LPBF · DED | Machine, feed system, layer strategy, and qualification stage |
| PSD candidates | 15–45 µm · 15–53 µm · 45–106 µm | Target process, equipment limits, and PSD test method |
| Process × PSD pairing | Not implied by this catalog page | Confirmed in the RFQ against the selected source and lot |
Powder screening data
A screening window for a better technical RFQ.
These grade-specific values help define the questions to ask. They are not stock data, a universal specification, or a lot certificate.
| Powder metric | Screening value | Qualification boundary |
|---|---|---|
| D10 | ≥15 µm | Method and lot to be confirmed |
| D50 | 30–40 µm | Method and lot to be confirmed |
| D90 | ≤60 µm | Method and lot to be confirmed |
| Sphericity | ≥0.90 | Method to be confirmed |
| Apparent density | ≥4.4 g/cm³ | Method and lot to be confirmed |
| Tap density | ≥5.0 g/cm³ | Method and lot to be confirmed |
| Flow | ≤18 s/50 g | Method and conditioning to be confirmed |
LPBF screening window. An Alloy 718 screening basis; final chemistry, PSD, and test methods are production- and lot-specific. Ask for the governing test method, sampling rule, source, production route, and lot-linked report in the quotation.
Application fit
Applications suited to technical review.
Turbomachinery hardware
High-temperature structures
Hot-side housings
Failure modes
Critical variables to verify before qualification.
- Heat treatment
- Laves phase and segregation control
- Temperature-specific testing
Evidence package
Request the documents that support the actual buying decision.
State the UNS, customer, or program chemistry basis plus the heat-treatment route and temperature-specific test requirements.
Certificates, technical data, sample reports, and partner-specific documents are supplied only when they correspond to the quoted source, grade, particle-size route, and lot.
Price and supplier RFQ
Price and availability follow the exact grade, PSD, evidence, and delivery scope.
A useful supplier comparison keeps the technical and commercial basis identical. Send the same inputs to avoid comparing different chemistry limits, powder routes, packages, or document scopes as if they were the same product.
Grade and acceptance basis
State the UNS, customer, or program chemistry basis plus the heat-treatment route and temperature-specific test requirements.
Process, machine, and PSD
State the target process, equipment constraints, particle-size range, and governing PSD method.
Quantity, packaging, and destination
Separate sample and production quantities; include package size, destination country, and target timing.
Lot evidence and source controls
List required COA, PSD, SDS, TDS, SEM, traceability, sampling, and production-route evidence.
