AR550 ballistic steel: material overview

When selecting AR550 ballistic steel, customers are often misled by fragmented or vague specifications found online, making it difficult to accurately determine whether the material meets their project requirements. BBN steel's AR550 ballistic steel is based on a low-alloy, high-strength composition and utilizes a precision-controlled quench-and-temper heat treatment process. This ensures high surface hardness while maintaining sufficient internal toughness, resulting in a balance of reliable ballistic protection and crack resistance.

AR550 ballistic steel also offers excellent suitability for cold working and welding; standard production processes—such as cutting, bending, and joining—can be performed successfully without the need for complex preliminary heat treatments. BBN steel provides comprehensive material documentation clearly outlining the chemical composition ranges and reference mechanical properties for each batch, enabling customers to verify and select the material based on the specific design requirements of their equipment.
