PowderRange 625 – Nickel 625 Powdered Metal
Premium Nickel-Base Superalloy Powder for Additive Manufacturing & 3d Printing
Overview
PowderRange 625 is a non-magnetic, corrosion and oxidation resistant, nickel-base superalloy engineered for advanced additive manufacturing processes. This exceptional material delivers outstanding strength and toughness across a temperature range from cryogenic to 2000°F (1093°C), making it ideal for the most demanding aerospace, automotive, and marine applications.
The alloy’s superior performance is derived from the solid solution effects of refractory metals—niobium and molybdenum—in a nickel-chromium matrix. With excellent fatigue strength and exceptional stress-corrosion cracking resistance to chloride ions, PowderRange 625 is the material of choice for mission-critical components.

Mechanical Properties
Typical mechanical properties at room temperature vary by heat treatment condition and build orientation. All testing performed in accordance with ASTM E8/E8M-16a (tensile), ASTM E23-18 (impact), and ASTM E18-19 (hardness). Values represent averages from minimum 5 samples across build plate extents.

Heat Treatment Options
Parts built from PowderRange 625 can be heat treated to modify mechanical properties within a specified range:
- Stress Relief (SR): 1900°F (1038°C) for 1 hour, air cool per AMS2774
- Solution Annealing (AN): 2150°F (1177°C), rapid air cool or faster for higher ductility per AMS2774
- Hot Isostatic Pressing (HIP): Minimum 14.5 ksi (100 MPa) at 2087°F (1141°C) for 240 minutes in argon to achieve full density
Corrosion Resistance Performance
PowderRange 625 withstands many corrosive environments. The nickel and chromium provide resistance to oxidizing environments, while nickel and molybdenum resist nonoxidizing atmospheres. Molybdenum specifically prevents pitting and crevice corrosion. Chloride stress-corrosion cracking resistance is excellent, and the alloy resists scaling and oxidation at high temperatures.
Note: The following ratings are for comparative purposes and derived from wrought product experience. Additive manufactured material may perform differently. Corrosion testing is recommended. Performance depends on temperature, concentration, pH, impurities, aeration, velocity, crevices, surface finish, and other factors.
