When they get to 220C they are going to fail pretty quick.
At those kinds of temperatures, oxidation is much faster, and you'll get heating and cooling stresses causing micro fractures as the load on the line goes up and down.
As the resistance increases even a little, the temperature will increase more, making the above effects even worse.
