Hot Rolled PVQ Steel P275N
P275N container steel plate is a steel grade in EN 10028, which is usually supplied in normalized condition. The tensile strength of P275N boiler plate is 430MPa to 530MPa (different thicknesses have different minimum strength points).
GNEE steel is a professional exporter and steel distributor of P275N vessel plate in China. We have more than 50,000 tons of P275N boiler steel plate in stock every month. We provide rust removal, cutting, punching, bending, welding and other services. For P275N steel boiler plate prices, please feel free to contact us by email or phone.
