Material Characteristics and Disadvantages are Evaluated of Nickel-based Alloy GH4169

Merit

It has good comprehensive properties in the temperature range of-253~650℃. The yield strength below 650℃ ranks first among the deformation high temperature alloys, and has good fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, as well as good processing properties and welding properties.

Shortcoming

SLM (Selective Laser Melting) molding process are easy oxidation and strict protective gas environment is required. Stress will be formed during the molding process, and thin wall parts are prone to deformation. When the shape of hollow parts, batch parts, number of threads exceeds 25, CNC process is included, etc., the delivery time needs to be confirmed offline.
