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 (Tc) lower than phase conversion temperature to make at least 740C. 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 |
