摘要： 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. A = 0.008 × ( % Cr ) 3 - 0.43 × ( % Cr ) 2 + 8.03 × ( % Cr ) + 6.8 × ( % Si ) + 10.9 × ( % Al ) + 0.56 × ( % Mo ) + 0.92 × ( % Ni ) ( 1 ) B = ( % Ni ) + ( % Cu ) + 0.6 × ( % Mn ) + 9.69 × ( % C + % N ) + 0.18 × ( % Cr ) - 0.11 × ( % Si ) 2 ( 2 )

摘要： High-rigidity stainless steel sheet is provided for CPU socket frames or retention covers that are lower in cost and have a better fastening performance compared to conventional ones. The stainless steel sheet has a Young's modulus ET in the T direction that is 210 GPa or above, an 0.2% yield strength σ0.2L in the L direction that is from 500 to 900 MPa, and an 0.2% yield strength σ0.2T in the T direction that is from 600 to 900 MPa, with the L direction being steel sheet rolling direction and the T direction being a direction perpendicular to the rolling direction (that is, a direction perpendicular to both the rolling direction and the sheet thickness direction). In the stainless steel sheet, the relationship between the Young's modulus EL (GPa) in the L direction and the Young's modulus ET (GPa) in the T direction is preferably EL≦ET−15.
