FIELD: various technological processes.
SUBSTANCE: invention relates to production of microwire from precision alloy of N70Kh10F8Ya7 grade. Multiple cold drawing is carried out to obtain a finished size, wherein heat treatment of wire of intermediate sizes is carried out in bell-type and drawing furnaces in a hydrogen medium at temperature of 1,050-1,100°C. After drawing, final thermal treatment of microwire is performed.
EFFECT: as a result, microwire is obtained from precision alloy of N70Kh10F8Ya7 grade with required mechanical and electrical properties, in particular, breaking force, relative elongation, electric resistance, temperature coefficient of electric resistance.
