What is the difference between plastic steel and manganese steel protective plates?
1 Answers
Plastic steel and manganese steel protective plates have the following differences: Plastic steel: 1. Advantages include a certain degree of elasticity, durability, good corrosion resistance, and relatively low noise. Plastic steel is lighter, moderately priced, and offers high cost-performance, making it economically practical. 2. The disadvantage is that its hardness is inferior to manganese steel, and it does not provide good protection against high-intensity impacts. Plastic steel becomes brittle in low winter temperatures and is more prone to breaking. Manganese steel: 1. Advantages include better resistance to collisions, stronger resistance to scratches, and greater impact resistance. 2. The disadvantages are that it is heavier, which can increase vehicle fuel consumption. Manganese steel is prone to rust and can develop noise over time. Additionally, manganese steel is more likely to produce resonance, affecting comfort.
