Soonv® 31 is a cobalt-base, high-temperature superalloy having high tensile and creep properties in precision casting. It is superior in stress-rupture properties to most alloys commercially available, especially at 1700 and 1800°F. Soonv® 31 is resistant to oxidizing and reducing atmospheres up to 1150°C (2100°F). Excellent resistance to thermal and mechanical shock. Mainly used in gas turbine engines in areas subject to hot gas erosion.
