Abstract
Bimetal strip the high-expansion element of which is an alloy which, in weight percent (w/o), consists essentially of up to about 0.50 w/o carbon, about 15-50 w/o manganese, up to about 2 w/o silicon, up to about 12 w/o chromium, about 10-35 w/o nickel, up to about 10 w/o cobalt and the balance iron except for incidental amounts of other elements which may include up to about 0.04 w/o phosphorus, up to about 0.04 w/o sulfur as well as other elements which do not significantly detract from the desired properties or result in the formation of ferrite or otherwise render the desired room temperature austenitic structure of the alloy unstable so as to significantly reduce the coefficient of thermal expansion.
