S690QL HSLA Low Alloy High Strength Steel Plate

 

S690QL high-strength steel plate is a high-strength low-alloy structural steel with high yield strength and excellent toughness. "S" steel is the standard name for structural steel, while the number "690" refers to the minimum yield strength of the steel plate. "QL" stands for "high ductility".

 

S690QL alloy steel is widely used in heavy-duty machinery, cranes, construction machinery, bridges, shipbuilding, mining equipment and energy fields; due to its high strength, light structure and good weldability, it has become the material of choice in engineering projects.

 

In addition, S690QL high-strength steel also performs well at low temperatures, so it can be used in applications exposed to cold weather conditions.
