To bend something you don t even need pure oxygen a propane blowtorch would work fine if it s big enough The flame in air is over the melting point of steel but not hot enough to be practically useful for welding Acetylene oxygen are needed for welding The reason you need the higher temperature flame is to localize the heat to a small area

Presumably you have to start with a low carbon mild steel or the rods will not bend easily You could extend the demo by smearing the central part of the rod with case hardening compound to introduce extra carbon before heating then clean up and check the strength and hardening before and after annealing As jtobako says the interference colours are also instructive yellow is a
