S460 high - strength structural steel plate is a kind of high - performance steel material, which is widely used in many fields due to its excellent mechanical properties. The following is a detailed introduction:

 

 

Types and Characteristics: It can be divided into S460N (normalized), S460M (thermo - mechanically rolled) and S460QL/QL1 (quenched and tempered). It has the characteristics of high strength, good toughness and excellent weldability. Its fine - grain structure can enhance impact resistance, and it also has reliable performance in harsh environments.

Application Fields: Widely used in the construction of high - rise office buildings, stadiums, exhibition halls and other landmark buildings. It is also suitable for the main beams, piers and other key parts of bridges, as well as the structural parts of heavy - duty mechanical equipment such as cranes, excavators and loaders. In addition, it is also used in offshore platforms, oil and gas refining and other fields.

 

 

 

 

 

 

 

S460QL1 is a high-strength bridge steel specified in the EN 10025-6 standard. The steel plate undergoes a two-step heat treatment process: quenching and tempering. It can also undergo Z-direction performance testing, with grades including S460QL1-Z15, S460QL1-Z25, and S460QL1-Z35. The through-thickness (Z-direction) performance is a crucial mechanical property of the steel plate, as it relates to the plate's ability to withstand forces acting along the thickness direction. In general, steel plates with additional Z-direction performance can better resist forces from various directions.

 

S460QL1 can be used normally in frigid regions, thanks to its low impact test temperature. It can maintain its mechanical properties and be used for long periods in environments as cold as -60°C. This steel plate is mostly used in high-strength structures such as bridge engineering.
