Nicloy 9 is a tough, impact resistant nickel alloy steel applicable to sub-zero temperature uses. It has high physical properties with excellent ductility. Its toughness is very high at low temperatures. At room temperature it is only slightly sensitive to temper brittleness. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness and fatigue. It also includes information on high temperature performance and corrosion resistance as well as heat treating, machining, and joining. Filing Code: SA-2. Producer or source: Babcock & Wilcox Company.
