1 Ballistic steels SECURE / SECURE M Plates for highest protection ThyssenKrupp Steel Europe Thinking the future of steel

2 SECURE ballistic steels excellent protective properties, high toughness and hardness ThyssenKrupp high protect ThyssenKrupp high protect SECURE SECURE M Protection for a diversity of applications Steel is a key material when it comes to protecting vehicles and buildings against the threat posed by firearms and explosives. The most important criterion in these applications is a high degree of security for occupants through ballistic protection. It is with this mind that ThyssenKrupp Steel Europe provides steels in the SECURE and SECURE M series, with excellent protective properties in combination with high toughness and hardness up to 600 HBW. SECURE steels have excellent cold forming properties despite their high degree of hardness, and guarantee good weldability with ferritic and austenitic consumables. Their characteristic alloying elements carbon, chromium, molybdenum and nickel, together with appropriate heat treatment by water or oil quenching and tempering, give the SECURE steels their high hardness and excellent ballistic protection properties. Weight-optimized design Tight thickness tolerances make it possible to design the ballistic protection on a weight-optimized basis and are therefore particularly interesting for designers where manufacturing and weight-related aspects are concerned. ThyssenKrupp Steel Europe produces heavy plate with particularly tight thickness tolerances with a maximum of 0.4 millimeters by using a state-of-the-art hot strip mill. This is approximately equivalent to halving the tolerances of a steel plate produced via the four-high mill. Innovative composites Combined protection concepts enable extensive protection properties and added savings in weight. Combining SECURE steels with fiber composite materials developed in cooperation with partners and customers synergizes the properties of different materials. Automobile designers can benefit in future from enhanced product characteristics. Highest quality standards The use of SECURE steels in safety-relevant spheres of application calls for extensive testing and individual final acceptance procedures. An in-house test facility and close cooperation with accredited ballistic test centers provide a sound basis for regular checks on and verification of ballistic properties and for the further development of these steel grades.

3 Advantages of SECURE ballistic steels at a glance Advantages of ballistic steels SECURE / SECURE M SECURE M 300/350 Specially developed to meet the requirements of MIL-DTL SECURE 400/500 / SECURE M 400/500 Standard grades for ballistic protection against hard-core ammunition. Steels offering an optimum combination of high hardness, cold formability and weldability. SECURE 450 / SECURE M 450 Besides high hardness, this grade offers excellent toughness properties and cold formability. Therefore particularly suited to providing protection against explosive charges (blast) or where high constructional demands are involved. SECURE ballistic steels are used for armored civilian vehicles. SECURE 600 / SECURE M 600 Ballistic steel with extremely high hardness to meet highest security requirements. Test conditions as per international specifications or according to customer requirements The Fox is a multifunctional wheeled vehicle armored with SECURE ballistic steel. DIN EN 1522/1063 PM 2000 NIJ STANAG 4569 UK DEF STAN MIL DTL MIL DTL NF A TL The Boxer s protective system is based on a self-supporting armored steel structure of SECURE steels with adapted protective modules.

7 SECURE ballistic steels optimal protection against ballistic attack and explosive SECURE ballistic steels make for optimal ballistic protection and a high level of safety for the occupants of civilian vehicles. SECURE steels with hardness grades 400, 450, 500 and 600 HBW are the ideal solution where ballistic protection in civilian applications is required. Optimal matching of the material to the specific requirements of each such application enables weightoptimized protective solutions even where the very tightest installation tolerances are called for. The SECURE 500 and SECURE 600 grades offer high or even extreme hardness levels coupled with good toughness, for example where the sides of a limousine need particular protection. Its exceptional toughness makes SECURE 450 the ideal solution for ensuring optimal underbody protection against explosive charges (blast). SECURE M for armored military vehicles required to guarantee best possible protection against explosions or ballistic threats. The SECURE M ballistic steels with hardness grades ranging from 300 to 600 HBW enable the design of fully protected armored vehicles with optimized basis weights besides which the excellent formability and weldability of these steels enable a broad diversity of development options. SECURE M 500 as basic protection for the bodywork and SECURE M 450 as underbody protection against explosive charges (blast) ensure comprehensive vehicle protection. The extremely hard SECURE M 600 steel is the preferred solution where adaptive add-on protection is required.
