1. Introduction
EN10025-6 S690QL is a high-strength steel plate that has attracted much attention due to its excellent mechanical properties and a wide range of applications. The chemical composition, mechanical properties, heat treatment state, low temperature impact test and main application scenarios of EN10025-6 S690QL will be discussed in depth in this paper, combined with the supply case of TJC Steel Group to provide more detailed and specific analysis.
2. Chemical Composition
The main chemical composition of EN10025-6 S690QL high strength steel plate includes iron (Fe), carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The content of these elements in steel is precisely controlled to ensure excellent mechanical properties and corrosion resistance. Among them, the carbon content is between 0.2% and 0.4%, which is used to enhance the strength and hardness of the steel. Silicon and manganese are used to improve the strength and toughness of steel. The content of phosphorus and sulfur is strictly controlled to reduce the brittleness of the steel.
3. Mechanical Properties
EN10025-6 S690QL high strength steel plate has excellent mechanical properties. Its tensile strength is usually between 690 and 790 MPa and its yield strength is between 590 and 690 MPa. In addition, the steel plate has high elongation and good plastic deformation ability. These excellent mechanical properties make EN10025-6 S690QL the material of choice for the manufacture of various heavy structures and machinery.
4. Heat Treatment State
EN10025-6 S690QL High strength steel plates are usually supplied in a normalizing or quenched state. Normalizing process by heating the steel plate above the critical temperature and slowly cooling, in order to obtain uniform microstructure and good cutting performance. The quenching treatment is to heat the steel plate to above the critical temperature and then cool it quickly to increase the hardness and strength of the steel. Depending on the specific application requirements, different heat treatment states can be selected to optimize the performance of EN10025-6 S690QL.
5. Low Temperature Impact Test
In order to evaluate the toughness of EN10025-6 S690QL at low temperatures, a low temperature impact test is required. This test evaluates the tough-brittle transition behavior of steel plates by measuring the impact absorption work at different temperatures. EN10025-6 S690QL can maintain good toughness at low temperatures and is suitable for applications in cold areas or extreme environments.
6. Main Application Scenarios
Due to its excellent mechanical properties and corrosion resistance, EN10025-6 S690QL high-strength steel plates are widely used in a variety of heavy structural and mechanical manufacturing fields. In the construction industry, it is used in the manufacture of high-rise buildings, long-span Bridges and large volume concrete structures. In the field of machinery manufacturing, it is used in the manufacture of heavy equipment, pressure vessels, ships and vehicles. In addition, EN10025-6 S690QL is also used in the manufacture of heavy structures and equipment in the petrochemical, nuclear and power industries.
