Material Properties of DX51D+AS Steel

characteristics:
1. High strength and toughness
DX51D+AS steel has high strength and good toughness, with tensile strength and yield strength reaching 510MPa and 340MPa respectively, and elongation at break exceeding 20%. This high strength and toughness enable DX51D+AS steel to have higher load-bearing capacity when subjected to complex loads and impacts.
2. Corrosion resistance
The surface of DX51D+AS steel has undergone special treatment and has good corrosion resistance. By coating a rust resistant layer on the surface of steel, the corrosion resistance of the steel can be effectively improved, thereby extending its service life.
3. Good processing performance
DX51D+AS steel has good processing performance and can be processed by various methods such as bending, stamping, and stretching. This excellent processing performance allows DX51D+AS steel to be widely used in the manufacturing of various shapes of products.
4. Excellent coating performance
The surface of DX51D+AS steel is flat, free from bubbles and impurities, and has good coating performance. During coating treatment, the adhesion and durability of the coating can be effectively improved, resulting in good decorative and anti-corrosion properties of DX51D+AS steel.
