PowderRange® X Datasheet | AMS7008

Description

PowderRange® X is a solid solution strengthened nickelchromium- iron base superalloy. It is not considered precipitation hardenable and achieves optimum material properties through solution treatments. It possesses high strength at room and elevated temperatures, and exceptional oxidation and stress corrosion cracking resistance. PowderRange® X displays significantly reduced crack susceptibility compared to the nominal alloy X composition. Its low carbon content and additional solid solution strengthening maximizes its compatibility with laser additive manufacturing processing. Although solution treatment is required for optimum high temperature performance, as-processed PowderRange® X displays mechanical properties equivalent to wrought material at both room and elevated temperatures.

Key Properties:

Exceptional strength and corrosion resistance to 2200°F (1204°C)

Laser-Powder Bed Fusion(L-PBF) As-built

PowderRange X is compatible with all commercially available L-PBF equipment.

To achieve mean, as-built density >99.9%, 30 μm layer thicknesses and Specific Energy ≥ 59 J/mm3 is recommended.

Solution Anneal and Age (Sol/Age)

Solution Anneal at 2150°F (1177°C) for 1 hour. To provide an adequate quench after solution treating, it is necessary to cool below 1000°F (540°C) rapidly enough to prevent precipitation in the intermediate temperature range. For thin geometries, rapid air cooling suffices. For heavier sections not subject to cracking, oil or water quenching is frequently required.

While generally not necessary to age, an aging treatment can be applied at 1400°F (760°C); hold 3 hours; air cool; reheat to 1100°F (595°C); hold 3 hours; cool in air.

Schedules tailored better to the AM process thermal history may be available. Please contact Carpenter Technology for information.

Hot IsostaticPressed condition(HIP/Sol/Pre)

We recommend HIP as standard practice for microstructure homogenization; removal of residual spatter-induced voids, trapped gas porosity in powder and keyhole porosities; as well as to heal any shrinkage-induced micro-cracks in the material.

To achieve up to full density (100%): Process components under inert atmosphere at not less than 14.5ksi (100 MPa) at approximately 2300°F (1260°C); hold at the selected temperature for approximately 240 minutes or more.

Follow with Solution and Age treatment as described above.

Machinability

To machine PowderRange X, we recommend using single-point tungsten carbide tools.

Increasing the speed and decreasing the feed results in better finishes. Excessive speeds are not recommended because the tools will break down.

A sulfur-base cutting fluid should be used. Ample coolant is suggested. Removal of cutting fluid is necessary before heat treating because the sulfur will offset the surface of the part. A rigid work piece and a rigid tool are necessary for optimum machinability.

Corrosion resistance

IMPORTANT NOTE: The following 4-level rating scale (Excellent, Good, Moderate, Restricted) is intended for comparative purposes only and is derived from experiences with wrought product. Additive manufactured material may perform differently; corrosion testing is recommended. Factors that affect corrosion resistance include temperature, concentration, pH, impurities, aeration, velocity, crevices, deposits, metallurgical condition, stress, surface finish, and dissimilar metal contact.
