WebAnother result of extreme temperatures is that material will expand or contract in proportion to the temperature, due to physics. So when the temperature rises in a steel structure the atoms start to vibrate more and more. This thermal agitation, in turn, leads to an increase in interatomic distances and thus causes an expansion in the material. WebThis is where a lot of people get confused. Steel is heated beyond its critical temperature for the annealing process. High temperatures used for annealing send steel into its austenite phase. During this phase, the grain quality of the steel changes. When hot steel is cooled and solid again, it cannot be used as is.
