General Product Description
Armour steel with high hardness and resistance to ballistic penetration.
Protection 500; it is supplied in order thickness of 4.00 – 40.00 mm and hardness range of 480-560 HBW.
Heat Treatment Condition
Quenched.
Protection 500 is not suitable for the secondary heat treatments by the user.
Tolerances
EN 10029” or “EN 10051” standards are applied in dimensional tolerances.
EN 10029 Class C Tolerance is guaranteed for thickness.
Thickness tolerance application is according to Narrowed Miilux Thickness Tolerance, which is more restrictive than EN 10029 Class C.
EN 10029 Class N, Steel Type H tolerances are guaranteed for the planarity.
Surface Condition
EN 10163-2 (Class B, Subclass 3) standard is guaranteed for the surface defects.
The surface of the Steel Plates is sandblasted according to ISO 8501-1 Sa 2½ quality.
Unless otherwise specified, shop primer is applied to Miilux products, which has been specially developed in order to provide very high welding and cutting speed after the sandblasting, with very low welding porosity and very low burning rate in the reverse area.
The shop primer protects the structure against atmospheric corrosion during the storage. It is applied at a thickness of 15-25 microns (these values are specified for a smooth test panel).
The paint type, which is used, has a performance suitable for the processes of welding and cutting.
Marking is done with Punch.
Marking is done with paint.
Product Certificate
Certification is performed according to the EN 10204 norm.
Test results are provided in English and/or Turkish in accordance with EN 10204-3.1.
For EN-10204-3.2 test certificates, at the time of order, it should be specified.

Brinell hardness test is applied on every armour steel in accordance with EN ISO 6506-1 principles. If the thickness of the hardness measurement area is thinner than 4.75 mm, the 5/750 HBW measurement method is used. For other thicknesses, the 10/3000 HBW method is used.
The hardness tests are performed on the machined surface at a depth of 0.50 – 1.00 mm from the armour steel surface.
Charpy V-Notch Impact Test is applied in perpendicular and parallel directions to the rolling direction in all castings and thickness* in accordance with EN ISO 148-1 principles.
For products thinner than 11.00 mm nominal thickness, sub-size samples are used. The determined minimum impact value is then proportional to the test specimen’s cross-sectional area. (*in order thickness of 6.00 mm and thicker armour steel)
Order-specific test requests should be discussed with Miilux Sales team at the order stage.
