Characteristics of EN10025-6 S690Q Steel
High Strength: The S690Q steel plate boasts an extremely high yield strength, reaching a minimum of 690MPa, with a tensile strength ranging between 770-940MPa. This high-strength property enables the S690Q steel plate to withstand heavy and dynamic loads, making it an ideal choice for structural applications.
Good Toughness: In addition to its high strength, the S690Q steel plate also exhibits excellent toughness. Its elongation rate is generally greater than 14%, allowing it to effectively absorb energy under heavy loads and impacts, thereby reducing the risk of brittle fracture. At low temperatures, such as -20°C, the impact toughness value exceeds 34J; at -40°C, it exceeds 27J.
Low-Temperature Resistance: The S690Q steel plate maintains good toughness and strength in low-temperature environments, making it suitable for use in cold regions.
Fatigue Resistance: The S690Q steel plate possesses good fatigue resistance, enabling it to maintain structural stability and safety under long-term cyclic loading.
Corrosion Resistance: After undergoing special anti-corrosion treatment, the S690Q steel plate exhibits excellent corrosion resistance, capable of withstanding oxidation and corrosion, thus extending its service life.
Weldability and Machinability: The S690Q steel plate demonstrates good weldability, allowing it to be connected and fixed to other steel materials or structures using various welding methods. It is also easy to machine and cut.
