And 650 degrees Celsius, is known as subcritical heat treatment. This heat treatment is typically used to improve the toughness and ductility of steel, while minimizing distortion and cracking. The specific temperature range of 550-650 degrees Celsius is often chosen based on the desired microstructure and properties of the steel being treated.
