Stainless steel material changes after annealing

Annealing one of the most important process parameters is the highest heating temperature (annealing temperature), most of the alloys annealing heating temperature selection is based on the alloy system phase diagram, such as carbon steel to the iron-carbon equilibrium diagram as the basis. All kinds of steel (including carbon steel and alloy steel) annealing temperature, depending on the specific annealing purpose of the different kinds of steel in the Ac3 above, Ac1 above or below a certain temperature. The annealing temperature of various non-ferrous alloys is below the solid-phase line temperature of the alloy, above or below the solid solubility line temperature.
