PSA Nitrogen for Metal Additive Manufacturing: Inert Atmosphere Requirements
Metal additive manufacturing builds components layer by layer from powdered metal. But at the temperatures required to melt titanium, aluminum, or stainless steel—typically 1,200°C to 1,900°C —these metals react violently with oxygen. A single oxygen molecule contacting molten metal forms an oxide inclusion that becomes a crack initiation site, a porosity defect, or a stress […]
