The thickness of our pressure vessel plates, A709 grade HPS50W bridge steel plate generally ranges 5 to 200mm. According to the working conditions and processing technology of the container, the pressure vessel plate must have good cold bending and welding performance; good plasticity and toughness; high temperature short-term strength or long-term strength performance. In order to make the container can withstand higher pressure and reduce the weight of the structure itself, in addition to high-quality carbon steel, pressure vessel plate is currently made of low-alloy structural steel.
The difference between Q195 steel and 20# steel: A709 grade HPS50W bridge steel plate, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A709 grade HPS50W bridge steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A709 grade HPS50W bridge steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
It is a modern high-tech professional enterprise integrating scientific research, A709 grade HPS50W bridge steel plate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A709 grade HPS50W bridge steel plate process technology development, technology transfer and related technical consulting and technical services.
