S890QL is a type of high-strength steel plate that is commonly used in structural applications, such as construction, heavy machinery, and offshore engineering. Here are some key properties and characteristics of S890QL steel: - Grade: S890QL - Material: High-Strength Low-Alloy (HSLA) Steel - Thickness: 4mm-150mm - Width: 1000mm-3000mm - Length: 3000mm-12000mm - Yield Strength: 890 MPa (min) - Tensile Strength: 940-1100 MPa - Elongation: 10% (min) - Impact Test: -40°C (optional) - Heat Treatment: Quenched and Tempered - Applications: - Structural steelwork - Heavy machinery - Offshore engineering - High-strength applications - Features: - High strength and toughness - Good weldability and machinability - Good corrosion resistance - Affordable price S890QL steel is known for its excellent strength, toughness, and weldability, making it a popular choice for structural applications. Note: S890QL is a designation from the European standard EN 10025-6, where: - S = structural steel - 890 = minimum yield strength (890 MPa) - Q = quenched and tempered - L = low notch toughness (optional) The exact composition and properties of S890QL steel may vary depending on the specific standard or specification being followed.
