HAYNES® NS-163® alloy

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 strengths that are unparalleled in any other wrought alloy product available today.
