SECURE Protection Steels

The most commonly used grades for protection against ballistic threats are SECURE 400® and SECURE 500®. Their excellent combination of high hardness and good toughness means they meet the requirements of all major national and international specifications.

The newly developed SECURE 600® meets the very highest requirements for ballistic protection. Thanks to its extremely high hardness, it fulfils maximum safety demands even in low thicknesses. These steels are usually supplied in the quenched and tempered (QT) condition and display a fine martensitic microstructure.

Among the high-hardness ballistic steels, SECURE 450® stands out with its improved toughness and excellent formability.

Ballistic steels from Ilsenburger Grobblech have been developed for a large number of applications and are subject to continuous improvement and optimization carried out in collaboration with users.
