S890Q is a European grade of high-yield-strength structural steel defined under the EN 10025-6 standard. It is a quenched (Q) and tempered (T) steel designed for high-load applications where weight reduction and high strength are critical.
1. Key Specifications
Material Number: 1.8940.
Yield Strength: Minimum 890 MPa (for nominal thicknesses up to 50mm).
Tensile Strength: Typically ranges between 940–1100 MPa.
Impact Testing: S890Q specifically requires a minimum impact energy value at temperatures not lower than -20°C. (Note: Variants like S890QL and S890QL1 are tested at -40°C and -60°C, respectively).
2. Common Applications
Due to its high strength-to-weight ratio, S890Q is used in safety-critical and heavy-duty industrial sectors:
Lifting & Earthmoving: Booms for mobile cranes, dumper bodies, and chassis for heavy road vehicles.
Structural Engineering: Bridge components, offshore structures, and supporting frameworks.
Energy & Pressure Vessels: Penstocks, spiral cases for power plants, and fixed or transportable storage tanks.
The price of S890Q steel plate is highly variable and significantly more expensive than lower-grade high-strength steels like S690Q. There is no fixed market price, but the following key factors and estimates provide guidance:
Key Price Drivers:
Order Specifications:
Thickness & Dimensions: Price increases substantially with thickness. Plates over 50–60 mm can be 50–100% more expensive per ton than thin plates (e.g., 10 mm).
Quantity: Large tonnage orders (e.g., full truckloads or mill orders) receive significant discounts.
Certification: Standard EN 10204 3.1 certification is included. Additional third-party testing (e.g., Lloyd's, DNV) or special impact testing at -60°C adds cost.
Market Factors:
Raw Material & Energy Costs: Alloying elements (Ni, Cr, Mo) and energy-intensive quenching/tempering make prices sensitive to commodity and energy markets.
Supply & Demand: Produced by a limited number of specialized mills (e.g., Dillinger, SSAB, voestalpine), so availability and regional competition affect pricing.
Processing & Logistics:
Processing: Cutting, drilling, or edge preparation adds cost.
Delivery: Location, shipping method, and Incoterms (e.g., EXW, FOB, delivered) are a major part of the final price.
Estimated Price Range (For Guidance Only):
S890Q typically costs 50–150% more than S690Q due to its more complex chemistry and processing.
Base Price Per Metric Ton: Approximately €2,000 – €4,000+ (or equivalent in USD/GBP).
Lower end: Large-volume orders of medium-thickness plates.
Upper end: Low-volume, very thick plates (>80 mm), small cut pieces, or orders requiring special certifications.
How to Get an Actual Quote:
Provide suppliers with a detailed Request for Quotation (RFQ) including:
Material grade: EN 10025-6 S890Q (specify sub-grade if needed, e.g., S890QL for -40°C toughness).
Dimensions: Thickness × Width × Length (in mm).
Quantity: Total weight or number of plates.
Certifications required.
Processing needs (if any).
Delivery destination and timeframe.

What is S890Q steel?
S890Q is a very high-strength quenched and tempered structural steel with a minimum yield strength of 890 MPa, designed for extreme load-bearing applications.
What are the properties of S890Q steel?
It offers exceptional strength, good toughness at low temperatures, and weldability with proper procedures, though it is more brittle than lower-grade steels.
Where is S890Q steel used?
S890Q is used in heavy-duty crane booms, advanced mining equipment, high-performance military vehicles, and specialized structural components where maximum strength-to-weight ratio is critical.
How does S890Q compare to S690Q?
S890Q has a higher yield strength (890 MPa vs. 690 MPa) but lower toughness and weldability, making it suitable for more demanding, lightweight designs.
What welding procedures are required for S890Q?
Welding S890Q requires strict preheating (often 150-200°C), low-hydrogen electrodes, controlled heat input, and post-weld stress relief to avoid cracking.
Is S890Q steel corrosion resistant?
No, S890Q is not corrosion-resistant and requires protective coatings like painting or galvanizing for use in exposed environments.
What standards cover S890Q steel?
It is primarily specified under the European standard EN 10025-6 for quenched and tempered high-strength structural steels.
Can S890Q be machined easily?
Machining S890Q is difficult due to its extreme hardness and strength; it requires robust tooling, slow speeds, and ample cooling.
What is the price of S890Q steel plate?
S890Q is significantly more expensive than lower-strength grades, with prices varying based on thickness, quantity, and certification requirements.
