Haynes NS-163® Cobalt Alloy

Alloy that brings high-temperature alloy performance at temperatures up to 2200°F (1204°C). HAYNES NS-163 alloy is a wrought cobalt-based alloy (Co–28Cr–21Fe–9Ni–1.25Ti–1Nb) for use in sheet and wire forms. Not only is this alloy fully fabricable and weldable, it achieves a level of stress-rupture strength that approaches the capabilities of the oxide-dispersion strengthened (ODS) alloys. This capability is developed through a unique new heat treatment under nitrogen which imparts a through-thickness dispersion-strengthening phase in the final part at thicknesses up to 0.100” (2.5 mm). This fabricable alloy achieves extremely high strengths versus other wrought alloy products.Data provided by the manufacturer, Haynes International, Inc.
