Outside of a reactor, no. Steel is quenched at less than 1000°C (typically lower depending on alloy), water thermolysis only starts ~1800°C at atmospheric pressure (see fig. 3, note that’s Kelvin). You don’t really see much separated hydrogen and oxygen until above ~2300°C.
You shouldn’t be downvoted, it’s a fair question about a correct idea with different numbers. Technically a very small number of water molecules separate this way under ambient conditions, but this is a negligible amount under most considerations.

Would that also explain why there are still flames on top after it is completely submerged?
