1. Introduction to P265GH.
P265GH is a European standard low-alloy high-strength structural steel plate, which belongs to a kind of boiler vessel plate, which is widely used in petroleum, chemical, electric power, boiler and other industries. Its implementation standard is EN10028, and the corresponding domestic material is 25mng.
2. Chemical properties of P265GH.
The chemical composition of P265GH steel plate includes carbon (C), silicon (Si), manganese (MN), phosphorus (P), sulfur (S) and other elements, of which the C content is controlled at 0Below 20%, the mn content is 080-1.40% and the Si content is 0Below 40%, the content of P and S is controlled at 0025% or less. This special chemical composition design makes P265GH steel plate have good mechanical properties and welding properties.
3. Mechanical properties of P265GH.
The yield strength of P265GH steel plate is 185-265 MPa, and the tensile strength is 410-570 MPa, which has high strength and good toughness. In addition, the welding performance of P265GH steel plate is also very good, its welded joint strength and toughness are high, the structure is stable, and it is not easy to produce welding cracks.
Fourth, P265GH application field.
P265GH steel plate is mainly used to manufacture various pressure vessels and boilers, such as reactors, separators, heat exchangers, storage tanks and other equipment in petroleum, chemical, electric power, gas and other industries. Due to its good mechanical properties and welding properties, P265GH steel plates play a key role in the manufacturing process of these devices.
In the production process, P265GH steel plate needs to go through multiple processes of treatment and processing, including smelting, continuous casting, hot rolling, controlled cooling, etc., to ensure the performance and quality of the steel plate. In addition, in order to meet different use requirements, P265GH steel plate can also be cut, bent, welded and other processing.
5. P265GH precautions.
It should be noted that the hardness of P265GH steel plate is relatively high, so special tools are required when cutting or machining. In addition, the corrosion resistance of P265GH steel plate is relatively weak, and it needs to be treated with anti-corrosion during use to prolong its service life.
VI. Conclusions. In conclusion, P265GH is a steel with excellent properties and is widely used in various industrial fields. Its good mechanical properties and welding properties make it play an important role in the manufacturing process of pressure vessels and boilers. In the future, with the continuous progress of science and technology and the continuous growth of industrial demand, the application field of P265GH steel plate will be more extensive.
