Definitions
- Thermostat metals conventionally embody metal layers of selected alloys which have been especially developed to display very high and very low coeicients of thermal expansion. When these metal layers are bonded together in work-hardened condition, the resulting thermostat metals have high flexivities and display a substantial degree of flexing movement in response to temperature changes. While such conventional thermostat metals are widely useful, it is found that in some applications, where the thermostat metals are arranged to display substantial flexing movement in response to temperature variations within a selected temperature range but are restrained against additional flexing movement while being subjected to relatively higher temperatures, the thermostat metals tend to undergo a change in thermal response characteristics during use. That is, it is found that stresses developed in the thermostat metals when they are heated to high temperature while restrained against flexing movement tend to cause a degree of permanent deformation in the thermostat metals.
- the metal layer 16 alternately comprises any of the austenitic stainless steels commonly designated as the SAE 200 and 300 Series of Stainless Steels, these materials preferably being utilized in the metal layer 16 in at least partially work-hardened condition and preferably in Work-hardened, stress relieved condition.
- SAE 200 and 300 Series of Stainless Steels these materials preferably being utilized in the metal layer 16 in at least partially work-hardened condition and preferably in Work-hardened, stress relieved condition.
