How is 3D Printing Nickel Alloy IN718 Powder produced?
Inconel718 alloy is a difficult-to-process material in the field of mechanical processing. It needs to go through a series of steps.
Warm-up
The surface of the workpiece must be cleaned before and during the healing process to keep the surface clean. If the heating environment contains sulfur, phosphorus, lead or other low melting point metals, Inconel718 alloy will become brittle. Impurities come from marking paint, chalk, lubricating oil, water, fuel, etc. The sulfur content of fuel should below. For example, the impurity content of liquefied gas and natural gas should be less than 0.1%, the sulfur content of city gas should be less than 0.25g/m3, and the sulfur content of petroleum gas should be less than 0.5%.
The heated electric furnace should have a more accurate temperature control ability, the furnace gas must be neutral or weakly alkaline, and the composition of the furnace gas should be prevented from fluctuating in oxidation and reducibility.
