The physical properties of 9% nickel steel cover elasticity, density, Poisson’s ratio and electrical resistivity. These properties apply to 9-Ni steel in both NNT and QT conditions of heat treatment.

• Modulus of Elasticity (at 70°F): 27000 ksi.
• Modulus of Elasticity (at -320°F): 30000 ksi.
• Density: 0.284 lb/in³ [7.86 g/cm³].
• Electrical Resistivity (at 70°F): 33.0 microhm-cm.
• Poisson’s Ratio: 0.30
