I've been baking out strings in an oven for a few years already. The result is stunning and lasts for quite some time. As a set of bass strings is expensive, it's worth the effort.

 

 

It's the same effect as boiling strings. You're just removing the skin and oils, but with the added advantage that you don't have any trapped water likely to rust the core. 

 

At 200°c I can't believe there's no effect on the metal.

It won't be getting anywhere near hot enough to anneal the steel, but it will be tempering the metal to some degree and maybe it's this that is helping rejuvenate the string?

as mentioned earlier, it's possible that some degree of hydrogen de-embrittlement may be occuring in the steel - it only requires temperatures around 200+ degC and can restore a measure of ductility to the metal

Mechanisms leading to embrittlement aren't fully understood yet, but one of the feasible scenarios could be a combination of stress to the metal plus acidic surface contact
