Hardened ballistic abrasion wear resistant steel plates are special steel plates that have the ability to withstand wear, abrasion, impact, and penetration caused by bullets and other projectiles. These plates are commonly used in the manufacturing of armored vehicles, military equipment, and buildings.
The most popular types of hardened ballistic abrasion wear resistant steel plates are the NM400, NM450, NM500, and AR500 steel plates. These plates are characterized by their high toughness, strength, and hardness levels, which make them suitable for extreme conditions.
The NM400, NM450, and NM500 plates are made from abrasion-resistant steel that has a nominal Brinell hardness of 400, 450, and 500 respectively. The AR500 plate, on the other hand, is made from high-carbon alloy steel that has been heat-treated to achieve a Brinell hardness of 500 or more.
Hardened ballistic abrasion wear resistant steel plates are useful in a wide range of industries, including mining, construction, defense, and transportation. They are also used in the manufacturing of heavy machinery, crushers, and shredders. These plates offer excellent protection against abrasion, wear, and impact, and can help improve the lifespan and durability of products and equipment.
