Armour Steel Plate

Armour Steel Plate

Hot rolled Steel Plates, Sheets and Coils (Armour steel) Suppliers, Stockist & Exporter in India.

Champak Industries is one of the leading manufacturers, exporters and suppliers of Armour Steel Plate.

Clients are looking for extraordinary assurance and wellbeing execution for their final results. Ramor plate has magnificent ballistic properties in mix with high hardness and quality. Ramor is created for applications, where impact insurance or high ballistic resistance is required.

Specification of Armour Steel Plate

  • Description of the steel grades
    Ramor armour steels are manufactured with a novel direct quenching process. With this method not only a good blast and ballistic protection is achieved, but also good flatness, surface quality and dimensional accuracy are obtained.

    Ramor 400 steel is designed to give protection against high pressures caused by explosions and blasts.

    Ramor 500 is the most suitable choice, when protection is needed against kinetic energy projectiles i.e. ballistic performance.

    The number of the designation indicates the average Brinell hardness value 400 and 500 HBW, respectively.

  • General technical delivery condition
    According to EN 10 021. Unless otherwise agreed, inspection document EN 10 204-2.2 is issued in English.

  • Chemical composition
    The chemical composition is stated in Table 2.

  • Mechanical properties
    Typical mechanical properties are presented in Table 3.
    the plate must take appropriate precautions to protect themselves and no outsiders must be allowed in the area. The safest location is usually by the bending ma- chine. The handling instructions of the steel supplier and safety instructions of the workshop must be adhered to in detail. New employees must receive appropriate train- ing before they are allowed to process hardened steels.

  • Materials testing
    Materials testing procedure is presented in Table 4. Recommended minimum plate thickness of Ramor 500 for different protection classes is presented in Table 5.

  • Heat treatment
    Heat treatment is not recommended. If tempering process is needed, please, contact technical customer service for further assistance.

  • Welding
    Ramor steels can be welded with common welding methods. Austenitic steel welding consumables are rec- ommended. Ferritic welding consumables can be used also, if the strength of the joint is important. If ferritic consumables are used, the need for elevated working temperature has to be studied in order to achieve fault- less weld joint.

  • Bending
    When cold forming Ramor 500 steels by bending, the minimum bending radius of the upper tool has to be 8 times the thickness of the material. The correspond- ing bending radius for Ramor 400 has to be 5 times the thickness of the material. Special care has to be taken to the working safety, when these steels are cold formed. Mechanical cutting is not suitable as an edge preparation process for bended parts.

  • Cutting
    Ramor steels are well suitable for laser and plasma cut- ting. Mechanical cutting can also be used, if the cutting shears/blades are hard enough and the equipment used is rigid. However, water jet cutting is preferred, because with this method the ballistic properties of the cut edge can be obtained.

  • Machining
    Ramor steels can be machined using rigid hard metal tools and rigid equipment. Sufficient lubrication has to be provided and special attention has to be paid to clamping of work piece. The cutting parameters should be chosen in the way that the vibration of the cutting tool and the work piece can be avoided, because vibration decreases the lifetime of the cutting tool considerably.

  • Occupational safety
    Special care must be taken in all stages of handling of hardened steels. Flanging is challenging due to the high strength and high flexural stresses of the plate. If the bending radius, for example, is too small and a crack is created in the bending point, the plate may fly from the bending tool in the direction of the bend. Those bending
