High Pressure Steel Sheet

The steel used for making boilers and high-pressure vessels is commonly referred to as pressure vessel steel or boiler steel. The characteristic feature of this steel is that it has high strength, good heat resistance, high pressure resistance, and good welding performance, which can withstand working conditions under high temperature and high pressure.

Common pressure vessel steels include SA-516, SA-537, SA-612, P355NL2, Q345R, etc. The characteristics of these steels are as follows:

SA-516: good heat resistance and high pressure resistance, widely used in the manufacture of boilers and pressure vessels.

SA-537: with high strength and heat resistance, suitable for working environment under high temperature and high pressure.

SA-612: with good welding performance and toughness, widely used in the manufacture of low-temperature pressure vessels.

P355NL2: with good heat resistance and pressure resistance, widely used in the manufacture of low-temperature pressure vessels and boilers.

Q345R: with good toughness and weldability, suitable for the manufacture of low-temperature pressure vessels and boilers.

These pressure vessel steels all have high strength, good heat resistance, high pressure resistance, and good welding performance, which can withstand working conditions under high temperature and high pressure. When selecting and using these steels, specific working conditions and requirements need to be considered.
