With state-of-the-art production facilities and a dedication to global standards, they’ve built a solid reputation as a reliable partner for high-strength quenched and tempered steels, especially S690QL, which is perfect for demanding structural and heavy-duty applications.
S690QL steel is a high-strength, quenched and tempered structural steel known for its remarkable toughness and weldability. Its typical chemical makeup features Carbon ≤ 0.20%, Manganese 0.80–1.70%, Silicon ≤ 0.80%, Chromium ≤ 1.50%, Nickel ≤ 2.0%, and Molybdenum ≤ 0.70%. On the mechanical side, it boasts a minimum yield strength of 690 MPa and tensile strength that ranges from 770–940 MPa, along with impressive impact toughness even at low temperatures (down to -40°C). These qualities make it an excellent choice for heavy-duty structural applications that demand strength, durability, and resilience against dynamic loads and harsh conditions.
