Bulletproof Steel Plate
Bulletproof Steel Plate
Abrasion occurs when materials are rubbed across one another over a period of time. Some abrasion is intentional, such as sanding, grinding, and blasting. However, unintentional abrasion can lead to component failure so it is important to use the proper materials to ensure that surface wear does not lead to unanticipated breakdown of structures or parts. While steel in general has excellent resistance to abrasion, not all steels are equal. There are several types of steels that are made particularly to prevent wear, known as abrasion resistant steels.
This is steel with a high tensile strength that can provide bulletproof capability and sufficient protection. It is widely used for the outer panels of armored personnel carriers, tanks and self-propelled guns/howitzers.
