Classification of Annealing Heat Treatment of Cast Iron Welding Platforms Description of Annealing Heat Treatment of Cast Iron Welding Platforms: Full Annealing and Isothermal Annealing: Full annealing, also known as recrystallization annealing, is generally referred to as annealing, which is mainly used for various carbons of hypoeutectoid components. Casting, forging and hot rolled sections of steel and alloy steel are sometimes used for welded construction. It is often used as a final heat treatment for some non-heavy workpieces or as a pre-heat treatment for certain workpieces. Spheroidizing Annealing: Spheroidizing annealing is mainly used for hypereutectoid carbon steel and alloy tool steel (such as steel cutting tools, measuring tools, and steel grades for molds). Its main purpose is to reduce hardness, improve machinability, and prepare for later quenching. Stress relief annealing: Stress relief annealing, also known as low temperature annealing (or high temperature tempering), is mainly used to eliminate residual stresses in castings, forgings, weldments, hot rolled parts, cold drawn parts, etc. If these stresses are not eliminated, it will cause deformation or cracking of the steel after a certain period of time or during subsequent cutting operations.
