18Ni300

WOCO identifies this item as 18Ni300 alloy powder, model / grade 18Ni300.

The source size is 15–53 µm.

The recorded tolerance field is 15–53 µm; confirm its dimension basis and units against the drawing.

The source material field reads: Fe Co.

Listed manufacturing route: Gas atomized.

Application & selection

Metal additive-manufacturing feedstock must be selected for the build process as well as the alloy designation. The supplied notes distinguish powder-bed fusion from directed-energy deposition and discuss the relationship between feedstock, spreading or feeding, and the resulting part.

Particle size and powder condition should be matched to the machine and build parameters. The local porosity discussion identifies both feedstock-related and process-related causes of voids, so printed density and other part properties require build-specific qualification.

Details to confirm for this product

• Alloy chemistry, machine and build process.
• Particle-size range, morphology, flow and powder handling requirements.
• Build qualification, heat treatment and part acceptance tests.
