Product Description

EN10028-3 P355NL1 for reactor

The EN10028-3 P355NL1 steel plate is a low-alloy high-strength structural steel compliant with European standards, mainly used for manufacturing pressure-bearing equipment, low-temperature pressure vessels, pipelines, and other devices.

Naming Convention:

“P” denotes European standard vessel steel plate, indicating compliance with European standards.
“355” signifies that the yield strength of the steel plate is not less than 355 MPa.
“N” indicates the delivery condition as normalized. Normalization is a heat treatment process that improves the microstructure and properties of the steel plate.
“L1” designates the steel plate as a low-temperature quality grade, enabling it to maintain good performance in low-temperature environments without easy brittle fracture.

Implementation Standard:P355NL1 steel plates are produced in accordance with the European standard EN 10028-3.

Dimensional Specifications :Thickness: 8MM to 150MM Width: 1600mm to 2500mm Length: 6000mm to 12000mm
