30CrNi3MoV bulletproof steel plate is a high-performance alloy steel plate specifically designed for ballistic protection applications, offering excellent bullet resistance, high strength, and good toughness. Its unique chemical composition and mechanical properties make it suitable for scenarios requiring reliable protection against projectile threats. Here's a detailed overview:

Chemical Composition & Key Alloying Elements

As indicated by its grade, 30CrNi3MoV contains the following main elements, which collectively contribute to its ballistic performance:

 

Carbon (C): Typically around 0.28%-0.35%, providing a foundation for strength and hardness through heat treatment.

Chromium (Cr): Enhances hardenability, corrosion resistance, and wear resistance, helping to improve the steel's ability to withstand projectile impact.

Nickel (Ni): Improves toughness, especially at low temperatures, preventing brittle fracture when subjected to high-velocity impacts.

Molybdenum (Mo): Increases hardenability and high-temperature strength, while reducing the risk of temper brittleness, ensuring stable performance under various conditions.

Vanadium (V): Refines the grain structure of the steel, enhancing strength and toughness, and contributes to wear resistance.

 

 

 

 

 

 

 

 

 

 

 

 

Mechanical & Ballistic Properties

High Tensile Strength: Generally exceeds 1200 MPa, enabling the steel plate to resist the penetration force of high-velocity projectiles.

Excellent Toughness: With a Charpy impact energy often above 60 J (at room temperature), it can absorb impact energy without cracking, crucial for stopping bullets effectively.

Good Hardenability: Can be heat-treated (quenched and tempered) to achieve a uniform and high-strength microstructure across the entire thickness of the plate, ensuring consistent ballistic protection even for thicker plates.

Ballistic Resistance: Designed to meet various ballistic standards (e.g., NIJ, STANAG), capable of stopping bullets from common firearms such as pistols, rifles, and even some high-powered weapons, depending on the plate thickness and heat treatment.
