P460QH Boiler Steel Sheet
P460QH pressure vessel steel plate is a European standard alloy container plate with high strength, good plasticity, toughness and weldability. It is widely used in the manufacture of pressure-bearing equipment such as petroleum and chemical industry.
P460QH pressure vessel plate material is usually delivered in quenched and tempered (quenched and tempered) state, with excellent mechanical properties and stability. P460QH vessel steel plate can also maintain stable performance in high temperature environment, suitable for the manufacture of high temperature pressure equipment.
