SOONV® alloy T-900 is a new cobalt base, Laves phase containing alloy with improved crack resistance over the traditional SOONV alloy T- 800.Unlike alloy T-800 which requires a preheat of 10000F or higher, the new T-900 powder can be welded with a preheat of 5000F.Like other alloys in the SOONV alloy family, it is hardened by an intermetallic compound, i.e., a Laves phase, not by carbides as in the more common hard facing materials. The wear test results indicate that alloy T-900 has similar wear resistance to alloy T-800 under low loads and outperforms the traditional alloy under high loads . Because of the fact that the Laves phase retains it’s hardness up to 14500F, the alloy has a good high temperature wear resistance. In addition, the high molybdenum content in the alloy imparts good localized corrosion resistance.
