This property ensures that the armor can withstand attacks and prevent penetration. 3. Toughness: Special steel needs to exhibit toughness, which allows it to absorb and dissipate the energy generated from impacts. This property helps to minimize the damage caused by projectiles and explosions. 4. Ballistic resistance: The steel should possess excellent ballistic resistance to effectively stop or deflect projectiles. It should be able to absorb and distribute the impact energy over a larger area, reducing the likelihood of penetration. 5. Corrosion resistance: Defense armor is exposed to various environmental conditions, including moisture and chemicals. Therefore, the special steel used in defense armor must have high corrosion resistance to ensure its longevity and effectiveness. 6. Weldability: The steel should be easily weldable to allow for the construction of complex armor structures. Weldability ensures that the armor can be conveniently assembled, repaired, or modified as per the specific requirements. 7. Heat resistance: Defense armor may need to withstand high temperatures generated from explosions or intense fire. Special steel should possess heat resistance to maintain its structural integrity and protective capabilities under such extreme conditions. 8. Lightweight: While maintaining the above properties, special steel should also be lightweight to ensure ease of mobility for soldiers and vehicles. The armor should not hinder movement or impose excessive weight burdens. Meeting these requirements is crucial to ensure the effectiveness and reliability of defense armor in providing protection to military personnel and assets.
