General Description of P355QL2
EN 10028-6 P355QL2 is a European standard specification for fine-grained, quenched and tempered steel plates intended for pressure vessels and boilers.
The P355QL2 is a low-temperature high-pressure vessel steel with excellent comprehensive performance, widely used in demanding working conditions in European and international engineering projects.
EN10028-6 P355QL2 Boiler And Pressure Vessel Steel Plate is a high-performance steel plate for critical pressure equipment, offering an optimal balance of strength, toughness, and weldability. It is widely used in energy, chemical, and cryogenic industries.
Key Features:
1. High strength & toughness at low temperatures (down to -50°C).
2. Good weldability (preheating may be required for thick plates).
3. Fine-grained microstructure for improved mechanical properties.
