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.
Increasingly, special measures are required in modern-day life to protect property and life. The risk of bullets and blasts requires protection steels with very special protective properties. Our SECURE Protection Steels offer this protection and are also characterized by advantages that set standards.
Ilsenburger Grobblech supplies SECURE Protection Steel according to customer requirements or according to the ballistic level STANAG 4569 (protection levels for occupants of logistics and light armored vehicles) and VPAM guideline APR 2006 for civilian vehicles. International ballistic requirements can be coordinated.
Due to the excellent combination of high hardness and good toughness, the steels meet the requirements of all major national and international specifications.
- Optimized combination of enormous toughness and hardness up to 600 HBW
- Good further processing through cutting, welding and cold and hot forming
- Weight optimization for hot rolled sheets thanks to very narrow thickness tolerances of max. 0.4 mm
- Quality inspections according to national, international and customer specifications possible
The quenched and tempered ballistic steels (QT) obtain their high hardness primarily as a result of a martensitic microstructure, with the maximum hardness in the steel being proportional to the carbon content. In addition, SECURE steels generally contain chromium, molybdenum, nickel and boron to ensure an even property profile across the thickness of the plate.
- Good cold forming
- Good welding taking certain measures into account: weld preparation, cooling times, choice of suitable filler metals, taking temperatures into account, etc.
- Drilling, countersinking and thread tapping possible using suitable tools and processing methods
- Thermal cutting: Depending on the plate thickness, different cutting methods are recommended (laser beam and underwater plasma cutting, abrasive water jet and flame cutting
