Scaffold plate and building structure boards steel sheet are accessible in different evaluations like straight review, low carbon evaluation and high carbon evaluation as indicated by the prerequisite of our client.
General steel range: The sentence about bridge plate, building plate and “straight review, low carbon and high carbon” grades describes a general range of structural steels, not S690 QL, which is one alloy quenched and tempered grade.
It would be ideal if you allude to the specialized subtle elements beneath alluding to S690 QL.
S690 QL - Grade Designation
The grade designation of S690 QL is the following: S = Structural Steel
690 = minimum yield strength (MPa)
Q = Quenching & Tempering
L = Low notch toughness testing temperature
Impact grade: “L” means impact energy is guaranteed at −40 °C (30 J longitudinal, 27 J transverse in the table below); “L1” is the −60 °C grade, which this page does not list.
S690 QL Plates: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Grade and standard | EN 10025-6 grade (S690Q, S690QL or S690QL1) or the named brand; state the edition and whether equivalent brands are acceptable. |
| Impact requirement | Charpy temperature and energy: “L” grades are tested at −40 °C and “L1” grades at −60 °C. |
| Thickness | Yield and tensile strength fall as thickness rises, so give the thickness range of your plates. |
| Welding | Preheat and consumables depend on carbon equivalent and thickness; ask for the mill’s welding recommendations. |
| Documents | EN 10204 3.1 or 3.2 mill certificate, with ultrasonic testing where specified. |
APPLICATION:
- Machine building
- Lifting equipment
- Heavy transportation
