Characteristic
Precision Alloy 36H brand with a predetermined coefficient of thermal expansion refers to Invars group. In its composition comprises 35−37% Ni, the balance being iron, doped silicon, manganese, copper, aluminum, vanadium, molybdenum. A similar mark 36H-VI was obtained by vacuum induction melting.
Using
Small coefficient of thermal expansion (1,5x10−6 1 / ° C at temperature of -80 to + 100 ° C) defines the area of application. This production of parts and workshop equipment, sensitive to small fluctuations in temperature. Often used in conjunction with an active layer consisting of other alloys (19NH, 20NG, 24NH, 75GND) for thermostatic bimetals different brands. Today 36H alloy of the most in demand the following types of rolled products:
— Cold-rolled strip
— Seamless pipe
— Hot-rolled sheet
— Hot rod
— Forged rods.
