An electric resistance material comprises an Fe-Cr-Ni alloy having composition of C up to 0.1%, Si up to 5%, Mn up to 6%, 9-32% Cr, 6-25% Ni, N up to 0.2%, 0-3% Mo, 0-4% Cu, 0-5% Al, 0-0.4% Ti, 0-0.4% Nb, 0-0.005% B and the balance being substantially Fe with the previsions that the value A defined by the formula (1) and the value B defined by the formula (2) are not less than 78 and not less than 14, respectively. The electric resistance material is high of resistivity with less temperature dependency, and a resistor made therefrom works well without noises during flow of electricity. <DF NUM="(1)">A=0.008x(%Cr)<3>-0.43x(%Cr)<2>+8.03x(%Cr)+6.8x(%Si) +10.9x(%Al) +0.56x(%Mo) +0.92x(%Ni) </DF> <DF NUM="(2)">B= (%Ni) + (%Cu) +0.6x(%Mn) +9.69x(%C+%N) +0.18x(%Cr)-0.11x(%Si)<2> </DF> <IMAGE> |
