Boiler Steel Plate P500Q For Pressure Vessel
P500Q boiler and pressure vessel steel plates need to undergo -20℃ low-temperature impact tests. Boiler steel P500QH belongs to the high-temperature performance steel series. In addition to low-temperature impact tests, high-temperature tensile tests are also required.
The P500Q pressure vesstel steel plates produced by GNEE Group are mainly used for boilers and pressure vessels. The minimum yield strength is 500Mpa, and the transverse impact test is performed at -20/-40/-60℃.
