BS EN 10028-2 P355Q P355QH P355QL1 P355QL2 Pressure Vessel Steel Plates
GNEE STEEL supplies high-quality EN 10028-2 pressure vessel steel plates in grades P355Q, P355QH, P355QL1, and P355QL2, designed for high-pressure applications requiring exceptional strength, weldability, and impact resistance.
P355Q is a quenched and tempered, fine-grain structural steel plate with excellent toughness, plasticity, and cold bending properties. These plates are specifically designed for pressure equipment and boilers, adhering to the EN 10028-1:2007+A1:2009 standard for dimensions, shapes, and tolerances.
Variants in the P355 Series
P355Q: Standard grade for high-pressure environments
P355QH: Enhanced impact toughness, suitable for low temperatures (0°C to -20°C)
P355QL1: Optimized for extremely low temperatures (up to -40°C)
P355QL2: Designed for ultra-low temperatures (down to -60°C)
Steel Grades: P235GH, P265GH, P295GH, P355GH, 16Mo3, 18MnMo4-5, 20MnMoNi4-5, 15NiCuMoNb5-6-4, 13CrMo4-5, 13CrMoSi5-5, 10CrMo9-10,12CrMo9-10, X12CrMo5, 13CrMoV9-10, 12CrMoV12-10, X10CrMoVNb9-1
EN 10028-2 steel plates are weldable non-alloy and alloy steels with elevated temperature properties for pressure equipment. The grades P235GH, P265GH, P295GH and P355GH are non-alloy quality steels, all other grades are alloy special steels.
