MARS 380 Armor Plate (4-110 mm) MIL-DTL-12560

At UTMK, you can order MARS 380 Armor Plate to execute projects of any complexity. This Rolled Homogeneous Armor (RHA) is a high-performance structural steel designed for maximum protection and processability. Its unique balance of certified ballistic properties, high impact toughness, and excellent workability makes MARS 380 the optimal choice for creating load-bearing structures that demand guaranteed reliability and manufacturing efficiency.

Technical Characteristics

MARS 380 armor steel is produced in compliance with stringent international standards, ensuring consistent chemical composition and mechanical properties from batch to batch. The key material parameters that define its performance characteristics are summarized in the table below.

Advantages of MARS 380 Armor Plate

Choosing MARS 380 steel provides not only a high level of protection but also significant manufacturing and economic benefits, which are critical for the successful implementation of complex projects.

• Superior Fabricability and Cost Reduction. MARS 380 steel offers excellent weldability and is suitable for cold bending, allowing for the creation of complex structures without the need for expensive preheating (for thicknesses up to 40 mm). This directly reduces production cycle times and energy costs, ensuring supply chain resilience and lowering the total cost of ownership.
• Certified Ballistic Performance. The material meets strict military standards, including MIL-DTL-12560 and ISO certifications, which guarantees reliable protection against a wide range of threats. Its unique quenching technology achieves excellent structural homogeneity, ensuring stable and predictable protective properties across the entire plate.
• Optimal Balance of Hardness and Toughness. Unlike ultra-high-hard steels that can be brittle, MARS 380 is engineered as structural armor. It not only stops a projectile (hardness) but also effectively absorbs blast and impact energy (toughness), maintaining structural integrity and protecting crew and equipment. This focus on technical compliance and risk mitigation is paramount.
• Versatility and Proven Experience. A wide range of available thicknesses (from 4 mm to 110 mm) and a successful track record in diverse applications—from main battle tanks and naval vessels to cash-in-transit vehicles and protective structures—confirm the versatility and reliability of this steel for both standard and custom engineering challenges.

Spheres of Application

Thanks to its balanced characteristics, MARS 380 plate is a primary material for manufacturing a wide range of protective products.

• Defense and Heavy Industry: Manufacturing of hulls and structural components for main battle tanks, armored personnel carriers, and other military vehicles in compliance with MIL-DTL-12560. Used in shipbuilding to create protected structures on frigates and patrol vessels.
• Commercial and Civilian Security: Armoring of VIP vehicles, cash-in-transit (CIT) trucks, and police cars. Used to produce bullet-resistant doors, window frames, bank counters, transaction windows, and safe rooms.
• Specialized Structures: Construction of fixed and mobile observation posts, sentry boxes, shelters, and protective barriers. Also used as targets for testing armor-piercing ammunition at firing ranges.
