Strength: 8.8 Material: carbon steel, alloy steel
Material: medium carbon steel
Material description: Chemical composition C (carbon): 0.18-0.23; Si (silicon): ≤ 0.10; Mn (manganese): 0.70-1.00; P (phosphorus): ≤ 0.030; S (sulfur): ≤ 0.035; B (boron): ≥ 0.0005
Surface treatment: colored zinc
Surface treatment content: Galvanized, requires passivation for better corrosion resistance. Passivation with colored passivation solution can obtain colored zinc.
