CORRECTION OF ALLOY COMPOSITION TO REACH SELECTED PROPERTIES IN HEATER AT LIMITED TEMPERATURE

摘要

FIELD: metallurgy.;SUBSTANCE: heater comprises heater section containing at least 50 wt % of iron, at least 6 wt % of cobalt, at least 9 wt % of chromium, and at least 0.5 wt % of vanadium, wherein said section features Curie temperature (T_c) lower than phase conversion temperature to make at least 740°C. Note here that heater section configuration ensures electric resistance when electric current varying in time is supplied in said section.;EFFECT: adjustable phase conversion temperature range.;19 cl, 1 ex, 4 tbl, 20 dwg
