NI-SPAN C is an age-hardenable iron-nickel-chromium-titanium alloy having a constant modulus, with advantages for control, measuring and timing equipment that temperature changes between -50 and 150 deg. F cannot weaken or soften. Temperature changes between -50 and 150 deg. F do not change its elastic properties. It is one of a series of four Ni-Span alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and machining. Filing Code: Fe-2. Producer or source: Henry Wiggin & Company Ltd.
