will there be any change in the chemical properties of m s wire during annealing?

Answer 1

There shouldn't be. Chemical resistance *might* increase some, but that's only assuming the grain boundaries in the wire are weak to corrosion. In annealing, the grains reform and grow, and grain boundaries aren't as numerous.

Answer 2

Normally not . But, it depends in what atmosphere, at what temperature and for what time.
If MS wire is annealed in a wet atmosphere containing cracked ammonia (with a dew point of +55 degrees C) at a temperature above 800 degrees C for long , the carbon in the steel will shift to wire surface ( Solid Diffusion) and react with Hydrogen. As a result, the carbon content in MS wire will go sown. Hence, the possibility of chemical properties change are always there.

Answer 3

sertainally not. the aneling has been given more resistance power to some extreem elements.
