Abstract

PURPOSE: To improve thermal fatigue life by keeping tempering temperatures at specific temperatures at the time of hardening then tempering the spray plate of an oil burner of a boiler manufactured of Mo-base high speed tool steel.
CONSTITUTION: The spray plate of the oil burner of a boiler for power is made of an Mo-base high speed tool steel. After this is heated and held at a 1,200W1,260°C temperature range, it is subjected to oil guench hardening. Further, at the time of tempering the same, it is heated and held at 610W650°C temperatures, after which it is air-cooled. Then, the service period up to the occurrence of thermal fatigue cracking by the thermal stress with repeated igniting and putting-out is considerably prolonged.
