MARS 600 Armor Plate (2,7-80 mm) MIL-DTL-32332 Class 1

At UTMK, you can source certified MARS 600 Armor Plate from a transparent and reliable supply chain partner. This ultra-high-hard (UHHA) 600 HBW steel from ArcelorMittal is engineered for maximum ballistic performance in critical defense and security projects. We provide fully traceable materials and precision processing services essential for applications compliant with ISO and military standards.

Technical Specifications

MARS 600 is a quenched and low-temperature tempered (below 180°C) steel, supplied as either quarto plate or cut-to-length sheet. It is manufactured to stringent standards, including MIL-DTL-32332 Class 1, and offers a unique combination of ballistic resistance and workability approaching that of 500 HBW grade steels. The table below outlines its key technical parameters.

Advantages of MARS 600 Plate

• Exceptional Ballistic Performance: Certified to meet and exceed MIL-DTL-32332 Class 1, this ultra-high-hard (UHH) steel provides superior resistance against high-velocity, armor-piercing rounds, ensuring compliance with top-tier NATO-level standards.


• Superior Workability (vs. 650 HBW): It offers an innovative balance of 600 HBW hardness with the toughness (up to 23J at -40°C) and workability (e.g., cold bending) of a 500 HBW plate. This significantly reduces fabrication risk for complex components.


• Outstanding Homogeneity and Flatness: Produced via a unique oil-immersion quenching process, the plate features excellent homogeneity, reduced residual stress, and superior flatness (e.g., 3 mm/m). This is critical for precision cutting and integration.


• High Multi-Impact Resistance: Engineered not just to stop a single projectile, but to maintain structural integrity and deformation capacity under multi-hit scenarios, which is critical for real-world ballistic threats.

Applications and Standards

MARS 600 is designed exclusively for ballistic protection applications, not for abrasive wear. Its uses span military, security, and high-stakes civilian infrastructure.

• Defense and Security Manufacturing:


• Structural components for Light Armored Vehicles (LAVs) and Armored Personnel Carriers (APCs).


• Fabrication of add-on armor packages for enhancing the protection level of existing military and police vehicles.


• Components for civilian armored vehicles (limousines, sedans, SUVs) and Cash-In-Transit (CIT) vehicles.


• Blast-resistant containers, guard shacks, shelters, and critical infrastructure protection elements.


• Compliance Standards:


• Components designed to meet European ballistic standards EN 1522 (Classes FB6/FB7 for doors/windows) and EN 1063 (Classes BR6/BR7 for glass), providing protection against armor-piercing (AP) rifle rounds.


• Vehicle structures engineered to comply with NATO STANAG 4569 (e.g., Levels 3-4) for kinetic energy and artillery threats.


• Private Security & Special Projects:


• Construction of modular safe rooms ("panic rooms") and armored closets for high-value residential and corporate environments.


• Ballistic hardening and reinforcement of existing doors, walls, and high-security window frames.

UTMK supports your supply chain with a complete portfolio of certified high-hardness steels. While MARS 600 offers excellent lightweighting capabilities, specific threats may require the extreme hardness of MARS 650 Armor Plate for perforated systems. For structural vehicle hulls requiring better ductility, we supply MARS 500 Armor Plate. For industrial abrasion resistance without ballistic certification, consider Hardox 600 Wear Plate. All materials are available with ISO-compliant cutting services.

Expert Consultation for Complex Armor Fabrication Projects

MARS 600 steel demands expert processing to maintain its ballistic properties. UTMK's advanced facilities are equipped for high-tolerance abrasive waterjet, laser cutting, and specialized cold forming, allowing you to outsource fabrication complexity and mitigate project risk.
