S890Q high strength steel plate

S890Q is an ultra-high strength quenched and tempered (Q&T) structural steel plate specified under EN 10025-6. The number "890" refers to its minimum yield strength of 890 MPa, while "Q" indicates delivery in the quenched and tempered condition, ensuring an excellent balance of strength, toughness, and weldability.

S890Q steel plate is widely used in heavy-duty load-bearing structures where weight reduction, high load capacity, and long service life are critical. Compared with conventional structural steels, S890Q allows designers to significantly reduce plate thickness while maintaining structural safety.

As a professional steel supplier, GNEE Steel provides S890Q plates with stable quality, strict EN standard compliance, and global export experience.

Ultra-high yield strength (≥ 890 MPa)

• Excellent strength-to-weight ratio
• Good low-temperature impact toughness
• Reliable weldability with proper procedures
• High resistance to fatigue and mechanical stress
• Suitable for harsh environments and heavy-duty service

These advantages make S890Q an ideal material for modern lightweight and high-performance engineering structures.

These properties ensure excellent performance in high-stress and low-temperature environments.

Thickness: 6 mm – 120 mm

Width: up to 3,500 mm

Length: up to 18,000 mm

Delivery condition: Quenched + Tempered (Q&T)

Custom cutting and fabrication services are also available upon request.

S890Q steel plate is widely used in industries requiring maximum strength with minimum weight, including:

1. Construction & Infrastructure

High-rise building structures

Long-span bridges

Load-bearing columns and beams

2. Lifting & Transportation Equipment

Mobile cranes

Tower cranes

Heavy-duty lifting arms and booms

3. Mining & Heavy Machinery
