Composition and properties of S690QL1 steel plate

Detailed explanation of S690QL1 steel plate:
S690QL1 steel plate belongs to a European grade, and can also be called quenched and tempered high-strength steel plate due to its heat treatment process state of quenching and tempering.

Chemical composition of S690QL1 steel plate:
S690QL1 steel plate → C (carbon) → ≤ 0.20;
S690QL1 steel plate → Si (silicon) → ≤ 0.80;
S690QL1 steel plate → Mn (manganese) → ≤ 1.70;
S690QL1 steel plate → S (sulfur) → ≤ 0.010;
S690QL1 steel plate → P (phosphorus) → ≤ 0.020;

Mechanical properties of S690QL1 steel plate:
S690QL1 steel plate → yield strength → ≥ 690MPa;
S690QL1 steel plate → tensile strength → 770-940MPa;
S690QL1 steel plate → elongation → ≥ 14%;

Delivery status of S690QL1 steel plate:
The S690QL1 steel plate is delivered using the heat treatment process of quenching+tempering, while meeting technical standards. After tempering and heat treatment, the strength of the steel plate can be improved, and the overall performance of the steel plate will also change.

Application fields of S690QL1 steel plate:
S690QL1 steel plate has relatively high strength and excellent processability, and can be used to manufacture various mining machinery, construction machinery, etc. In terms of the yield strength of the steel plate, the yield strength of S690QL1 steel plate is similar to that of China's national standard Q690.
