Learn About the Benefits of Normalizing Steel Beyond Its normalized high strength low alloy structural steel plates Heat treatment

Heat treatmentis a process in which metals are heated and cooled to change their structure. The changes to the metals' chemical and physical properties differ based on the temperatures that they are heated to and how much they're cooled down afterward. Heat treatment is used for a wide variety of metals. Metals are typically treated to improve their strength, hardness, toughness, ductility, and corrosion resistance.
