WebPhysical Properties of Nichrome. The ultimate tensile strength of nichrome is 105,000 PSI (Pounds per Square Inch) and yield strength is around 50,000 PSI. Following are some of the other physical properties of nichrome. Electrical Resistivity at room temperature: 1.0 x 10 -6 to 1.5 x 10 -6 ohm m. Thermal Conductivity: 11.3 W/m o C. WebAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.
