General Description of P690QL1
EN10028-6 P690QL1 is a high-strength quenched and tempered (Q&T) fine-grained steel plate designed for pressure equipment, particularly where high yield strength, toughness, and weldability are critical. It is commonly used in boilers, pressure vessels, and structural components subjected to extreme conditions.
Advantages of EN10028-6 P690QL1 Boiler And Pressure Vessel Steel Plate:
✔ High strength-to-weight ratio (reduces material usage)
✔ Excellent low-temperature toughness (down to -60°C)
✔ Good weldability (with proper procedures)
✔ Resistant to brittle fracture (critical for pressure applications)
