P295GH (17Mn4) Pressure Vessel Steel Plate
P295GH boiler steel plate is a European standard pressure vessel steel plate with good comprehensive performance and is widely used in the manufacture of boilers and pressure vessels.
Performance characteristics of P295GH vessel plate
Strength and rigidity: P295GH boiler plate has high yield strength and tensile strength, and can withstand large external forces while maintaining good rigidity.
Plasticity and toughness: P295GH pressure vessel steel has good plasticity and toughness, and can maintain sufficient plasticity even when subjected to force, is not prone to fracture, and can maintain structural integrity when subjected to impact or vibration.
High temperature resistance: P295GH pressure vessel plate can maintain stable mechanical properties under high temperature environment, and is suitable for high temperature pressure vessels and boiler equipment.
P295GH pressure vessel steel plate is widely used in the manufacture of pressure vessels in the petroleum, chemical, electric power, shipbuilding and other industries, such as storage tanks, reactors, heat exchangers, boilers, nuclear island steel containment, oil and gas tanks, liquefied gas tanks and other equipment.
