High - strength Mechanical Properties
Yield Strength: The “280”, “350” and “450” in the steel grade represent the yield strength of the steel plate, which are 280MPa, 350MPa and 450MPa respectively. S450GD+Z is suitable for scenarios requiring high - strength load - bearing, while S280GD+Z can meet the strength requirements of general structures.
Tensile Strength: They all have relatively high tensile strength. Generally, the tensile strength of S280GD+Z is usually higher than 400MPa, and the tensile strength of S350GD+Z and S450GD+Z is even higher, which can ensure the stability of the steel plate under tension.
Elongation: These steel plates have good plasticity and toughness. For example, S450GD+Z has good elongation, which can effectively resist external impact and extrusion, and can also adapt to the processing of complex - shaped components.
Excellent Corrosion Resistance
Galvanized Coating: Adopting the hot - dip galvanizing process, a dense pure zinc coating is formed on the surface of the steel plate. The coating has strong adhesion, which can effectively isolate oxygen, moisture and corrosive media. The zinc layer thickness is usually 5 - 25μm, and the coating weight can reach 20 - 275g/m², which can extend the service life of the steel plate.
Good Processing Performance
Formability: They can be easily cut, bent, punched and welded. For example, in the manufacturing process of automotive body panels, these steel plates can be processed into various shapes according to needs. Appropriate welding processes (such as gas shielded welding, submerged arc welding) can obtain high - quality welds, which is convenient for manufacturing various structural components.
