P500QH Boiler Quality Steel Plate
P500QH boiler quality plate is characterised by high strength, good plasticity and toughness, and resistance to fatigue, low temperature and corrosion.
The yield strength of P500QH pvq plate is much higher than that of ordinary carbon steel, and at the same time, it has excellent fatigue resistance, which allows it to work normally in a variety of environments, and its corrosion resistance is also very good.
