Introduction to P460QL1 1.8872 Steel Plate

P460QL1 (EN 10025-6 designation) / 1.8872 (Werkstoff number) is a high-strength quenched and tempered steel plate engineered for critical structural applications requiring:

Exceptional toughness at temperatures down to -60°C

Superior weldability with low carbon equivalent (CET ≤0.43)

Resistance to lamellar tearing (Z35 certification available)

Certified to EN 10025-6 standards, this steel is widely used in offshore energy, cryogenic storage, and heavy equipment manufacturing.
