Features of S250GD+Z
High strength: The minimum yield strength of S250GD+Z is 250MPa, which has a high bearing capacity and is suitable for structural parts that need to bear large loads.
Excellent corrosion resistance: The galvanized layer can effectively prevent the base metal from being affected by the external corrosive medium, thus extending the service life of the material. In wet, rainy and other harsh environments, S250GD+Z can still maintain good corrosion resistance.
Good mechanical properties: In addition to high strength, the S250GD+Z also has good plasticity and toughness, which can easily cope with various deformation requirements during processing. Its tensile strength, yield strength and impact toughness and other indicators are in line with national standards.
Excellent processability and weldability: The S250GD+Z can easily perform cold forming, deep drawing and cutting operations during processing to meet various processing needs. At the same time, it has excellent welding performance and can be reliably connected with other materials, which provides convenience for the manufacture of various complex structures.
Decorative performance: S250GD+Z galvanized coil surface smooth, flat, after polishing, painting and other treatment, can show a beautiful appearance, suitable for a variety of decorative projects.
Chemical composition of S250GD+Z
The chemical composition of S250GD+Z mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements, the specific content is as follows (take a test result as an example, different batches or manufacturers of products may be slightly different) :
Element content Range (Wt%)
Carbon (C) ≤0.25
Silicon (Si) ≤0.6
Manganese (Mn) ≤1.7
Phosphorus (P) ≤0.1
Sulfur (S) ≤0.045
In addition, because the S250GD+Z is galvanized steel, its surface is also covered with a layer of zinc, and the thickness and quality of the zinc layer are also important factors affecting its performance.
Delivery status of S250GD+Z
S250GD+Z is usually delivered in hot-rolled, galvanized condition. The galvanizing process includes hot dip galvanizing, in which steel is immersed in a molten zinc solution at high temperatures so that a uniform zinc layer is formed on the surface of the steel. This treatment not only improves the corrosion resistance of the steel, but also increases its aesthetics. The specific delivery status may vary according to user needs and the manufacturer's production process, such as hot rolling, normalizing, tempering and other heat treatment states may also appear.
Application range of S250GD+Z
S250GD+Z is widely used in many fields due to its excellent performance:
Construction field: In the field of construction, S250GD+Z is widely used for waterproof, thermal insulation and decoration of roofs, walls, doors and Windows. Its high strength and corrosion resistance can effectively enhance the stability and durability of the building.
Transportation: The S250GD+Z is also widely used in the field of transportation. For example, highway guardrail, bus stop sign, vehicle shell and other parts need to use the S250GD+Z. Its excellent corrosion resistance and mechanical properties make it widely used in the field of transportation.
Mechanical field: In the mechanical field, the S250GD+Z is used to manufacture enclosures and internal structures for various mechanical equipment. Its excellent mechanical properties and processing properties make it have a wide application prospect in the machinery manufacturing industry.
In the field of electrical appliances, the S250GD+Z also plays an important role. For example, the S250GD+Z is required for the shell and internal structural parts of electrical products such as air conditioners, refrigerators, and washing machines. Its excellent mechanical properties and processability can guarantee the safe and stable operation of electrical products.
