Ideal for nuclear energy & marine applications.
Material & Process Capability
Inconel® 625 is a solid solution strengthened nickel-based superalloy. It is characterized by having excellent tensile, creep, and rupture properties, particularly at high temperatures. IN625 has good corrosion resistance in various corrosive environments.
The Velo3D intelligent additive printing solution uniquely enables companies to build the parts they need without compromising design or quality – resulting in complex parts higher in performance than traditional casting techniques or other additive methods.
In addition to its strength, IN625 is characterized by its superb fatigue, creep, and rupture resistance in extreme environments. IN625 is difficult to shape and machine using subtractive manufacturing techniques.
This data sheet specifies the expected mechanical properties and characteristics of this alloy when manufactured on a Velo3D Sapphire® System. All data is based on parts built using Velo3D standard 50 μm layer thickness parameters, using Praxair Tru-Form 625-2, a Velo3D-approved powder.
Parts built from IN625 on a Sapphire System can be heat treated like those manufactured by other methods.
