S690QL1 steel plate specifications

S690QL1 steel plate is a high-strength quenched and tempered structural steel plate. S690QL1 structural steel is used in large-scale engineering structures and heavy machinery, such as bridges, ships, vehicles, oil rigs, construction machinery and so on. The steel plate S690QL1 has high strength and toughness, good cold formability and weldability. It is suitable for use in temperatures ranging from -40°C to -60°C.

The chemical composition of S690QL1 steel plate is as follows: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.70, P ≤ 0.025, S ≤ 0.020, Nb ≤ 0.05, V ≤ 0.12, Ti ≤ 0.05, Al ≥ 0.015. The mechanical properties of S690QL1 steel plate are as follows: tensile strength ≥ 690MPa, yield strength ≥ 690MPa, elongation after fracture ≥ 15%.

EN10025-6 S690QL1 Carbon steel plate is a kind of high-strength quenched and tempered structural steel plate. It is made of hot-rolled steel plate with a thickness of 8-200mm. Due to its high strength and toughness, S690QL1 steel plate is suitable for use in large-scale engineering structures and heavy machinery. It has good cold formability and weldability. In addition, S690QL1 steel plate has good corrosion resistance and wear resistance, low temperature impact toughness, and excellent fatigue resistance.

Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various S690QL1 steel plate steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the S690QL1 steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between S690QL1 steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
