Well as a basic metallurgic principle, anytime steels or alloys are heated (notably more than in day-to-day temperature changes) their strength qualities do change. How much is hard to say in this case. An idea of how much heat it has been exposed to can be found from heat coloring of the parts. For example if they have been colored bluish, it can suggest very high temperatures that may weaken alloys significantly.
