S690QL Steel Introduction
S690QL is a hot rolled structural steel, with high yield strength, delivered in the quenched and tempered condition.
The steel name or the steel number of S690QL:
S standards for structural steel
690 indicates the minimum specified yield strength for thickness ≤50mm expressed in MPa
Q for delivery condition of quenched and tempered
L for the quality with specified minimum values of impact energy at temperatures not lower than -400C
S690QL Steel Delivery state: quenched and tempered condition (QT)

a. Depending on the thickness of the product and the manufacturing conditions, the manufacturer may add to the steel one or several alloying elements up to the maximum values given in order to obtain the specific properties.
b. There shall be at least 0.010% or a grain-refining element present. Aluminum is also one of these elements. The minimum content of 0.010% applies to soluble aluminum, this value is regarded as attained if the total aluminum content is as least 0.013%; in case of dispute the soluble aluminum content shall be determined.
