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.

Additive manufacturing process guidance


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/Age)

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.


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.

Solution Annealand Age Condition (Hom/Sol/H900)

After either homogenization or HIP’ing, Solution Anneal at 1900°F (1038°C) per ASTM A564/A564M for 0.5 hours, cool to below 90°F (32°C) to achieve complete transformation to martensite.

Sections under 3in. (76mm) can be quenched in a suitable liquid quenchant (e.g. water or oil) and sections over 3in. (76mm) should be rapidly air cooled. It is recommended not use this Solution Annealed condition, without age hardening, for the final product due to susceptibility to stress-corrosion cracking.

After Solution Anneal, age material as desired per ASTM A564/A564M, e.g. 900°F (482°C) for 1 hour and air cool.


PowderRange 15-5PH is readily machined in both the solution-treated and various age-hardened conditions. In the solution-treated condition, it machines similarly to stainless steel types 302 and 304.

When using carbide tools, surface speed feet/minute (SFPM) can be increased between 2 and 3 times over the high-speed suggestions. Feeds can be increased between 50 and 100%.
