Haynes International, Inc. is pleased to announce the development of HAYNES® NS-163® alloy, an alloy that brings a new level of 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 strengths that are unparalleled in any other wrought alloy product available today.
