According to a Google source, carbon steel (type AISI 1010 steel) has a resistivity: ρ = 14.3 x 10-8 Ωm at 20 °C.
Does the resistivity of carbon steel vary significantly depending on its carbon content, heat treatment, relaxation properties etc?
I am trying to determine the electrical resistivity properties of 1/2" diameter, 7-wire, grade 270 ksi prestressing strand used in prestressed concrete. Cross sectional area = 0.153 in2 (98.7 mm2)
I tried using a multimeter with a known length of strand to calculate the resistance but the results did not seem accurate - I think the multimeter range is not sensitive enough.
