A709 grade HPS50W bridge steel plate,The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the , steel plate used for the container must have good cold bending and welding performance Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance,A709 grade HPS50W bridge steel plate.
Compared with , boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
The main applications of normalizing are as follows:① For low carbon steel, A709 grade HPS50W bridge steel plate. 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.
