It delivers an optimal combination of resistance and excellent workability, enabling complex fabrication while ensuring full technical compliance for your critical projects.

Technical Specifications

Below is a table of the primary guaranteed and typical mechanical properties for MARS 500 armor steel, manufactured in accordance with military and industrial standards.

Benefits of MARS 500 Armor Plate

• Superior Ballistic Resistance. A guaranteed hardness of 477-534 HBW ensures dependable performance against ballistic threats and fragmentation, exceeding the rigorous requirements of MIL-DTL-46100.


• Excellent Fabricability for Complex Designs. The optimized chemical composition provides superior weldability and cold-forming capabilities. This reduces fabrication risks and allows our facility to perform high-precision processing, helping you outsource complex components efficiently.


• High-Impact and Blast-Load Toughness. With a high Charpy-V impact value (≥ 24 J at -40°C), MARS 500 resists shattering upon impact, maintaining structural integrity against explosive threats, not just penetration.


• Guaranteed Compliance and Supply Chain Transparency. We deliver plates with full certification (e.g., EN ISO 6506-1 for hardness, EN 10163 for surface). This ensures complete technical compliance and material traceability, supporting your project's quality assurance and ESG requirements.

Application Fields

• Manufacturing of light-to-medium-weight armored vehicle structures, certified to meet standards such as STANAG 4569 (Levels 1-3).


• Certified add-on armor packages for heavy vehicles, providing documented compliance for defense contracts.


• Fabrication of blast-resistant containers, personnel shelters, and critical structural components.


• Civilian protection and security applications, including armored sedans, cash-in-transit (CIT) vehicles, safe rooms, and ballistic-resistant doors compliant with EN 1522 / EN 1063.
