Welcome to Dang Steel Manufacturer and Suppliers, based in Da Nang, Vietnam! We pride ourselves on being a top-notch provider of high-strength structural steels, featuring premium EN 10025-2 S690Q sheets and plates. Our reputation for outstanding quality, precise cutting, and prompt delivery has made us a go-to choice for various industries, including construction, heavy machinery, and infrastructure projects. Our S690Q products adhere to rigorous international standards, guaranteeing exceptional mechanical performance and durability, even in the toughest conditions. With a strong commitment to customer satisfaction, we offer technical support, custom sizes, and dependable sourcing solutions, making us a trusted partner for high-yield steel needs throughout Vietnam and beyond.
When it comes to composition and mechanical properties, EN 10025-2 S690Q is a high-yield structural steel grade boasting a minimum yield strength of 690 MPa. It generally contains carbon (≤0.20%), manganese (≤1.70%), silicon (≤0.80%), along with micro-alloying elements like chromium, nickel, molybdenum, vanadium, and boron. This steel delivers impressive tensile strength (770–940 MPa) and maintains good notch toughness, even in colder temperatures. S690Q undergoes heat treatment through quenching and tempering, which boosts its strength-to-weight ratio, weldability, and overall structural integrity. It’s perfect for demanding load-bearing applications where strength and reliability are paramount.
