The main applications of normalizing are as follows:① For low carbon steel, P355GH boiler steel elongation. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

The addition of Ca element in steel such as p355gh boiler steel elongation can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
p355gh boiler steel elongation, SA203 Gr.E plate is widely used in the production and processing of cryogenic separation processing, air separation and liquefied gas storage equipment. In recent years, the large-scale low-temperature equipment such as CO2 absorption tower, H2S absorption tower, H2S concentration tower and methanol washing tower in domestic coal chemical projects are mainly manufactured with SA203 Gr.E material, and the maximum thickness currently used is 110mm.
