Al 0.2 to 0.4%
Mg > 0.001 to 0.01%
V <=0.1%
W 0.25 to 1.0%
Co 0 to < 0.5%
Fe remainder and constituents resulting from a production process, wherein:
the sum, in
mass%, of Mo + W is between 2.2 and 3.5%, the sum, in mass%, of Cr + W is
between 1.0
and 2.0%, the sum, in mass%, of Si + Mn is < 0.1%, and the alloy has a thermal
expansion
coefficient of < 4 x 10 -6/K in the temperature range between 20 and
200°C.
L'invention concerne un alliage fer-nickel ayant la composition suivante (en pourcentage en masse) : C 0,05 à 0,5 %, Cr 0,2 à 2,0 %, Ni 33 à 42 %, Mn < 0,1 %, Si < 0,1 %, Mo 1,5 à 4,0 %, Nb 0,01 à 0,5 %, Al 0,1 à 0,8 %, Mg 0,001 à 0,01 %, V max. 0,1 %, W 0,1 à 1,5 %, Co max. 2,0 %, le reste étant constitué de Fe et d'impuretés résultant de la fabrication.
