Armor 500 and 550 Ballistic Steel Plate

Two hardness classes from one stock so each zone gets the level it actually needs

Armor 500 550 steel plate covers two hardness classes of quenched and tempered ballistic plate, comparable to a Ramor 500 type bulletproof steel plate. Security fabricators and vehicle builders choose between the two classes when part of a structure needs the higher class and the rest does not have to carry its cost or its forming difficulty. Holding both classes in one stock lets a designer step hardness up only on the exposed face instead of specifying the harder plate across the whole assembly. Thickness runs from 2mm to 100mm and panels are cut to size on a laser machine or a water jet before shipment.

Why It Is Specified

Key Benefits of Armor 500 550 Steel Plate

Two Hardness Classes on One Order

Armor 500 and Armor 550 ship from the same stock. A design can put the higher class on the exposed face and the lower class behind it without opening a second supply chain.

Cost Follows the Class You Actually Need

The higher the hardness of the armor steel plate the higher the price. Splitting a structure between the two classes keeps spend on the zones that are exposed.

Ballistic Steel Band of 500-600 HB

Both classes sit in the ballistic steel hardness band of 500-600 HB while structural steel may reach only half of that figure.

Yield 1250 MPa and Tensile 1600 MPa

Stated yield strength is 1250 MPa and tensile strength is 1600 MPa. The source material attributes greater multi hit capacity to this combination than to other steel.

Formability Considered at Design Stage

As hardness rises the ease of folding welding and cutting drops. Keeping the lower class on parts that need bending makes the fabrication route workable.

Panels Cut Before They Reach Your Shop

Every fixing hole and profile is cut here on a laser machine or a water jet. What arrives is a panel, not a plate waiting for equipment you may not have.

Problems It Solves

What This Material Removes From Your Process

Paying Top Class Prices Across a Whole Structure

Specifying the harder class everywhere raises cost on panels that are never exposed. Two classes from one stock let the specification follow the exposure map of the design.

Structures That Cannot Be Formed at All

A whole assembly in the hardest available plate becomes almost impossible to fold and weld. Keeping the lower class on formed sections leaves a buildable route.

Two Suppliers for Two Classes

Splitting the classes across suppliers doubles the paperwork and the inspection route. One order covers both with one test report route.

Holes That Cannot Be Made After Delivery

Hardened plate resists drilling and punching in a general shop. Fixing holes are cut here on laser or water jet to the positions on your drawing.

Application Scenarios

Where It Is Used

Armor Doors and Armor Walls

Building protection where the exposed leaf takes the higher class and internal linings take the lower one.

Riot and Money Transport Vehicles

Riot vehicles and money transport vehicles where sides doors and floors are protected to different levels.

Ballistic Windows and Frames

Window surrounds and frame sections built around a glazed ballistic unit.

Bank Counters and Confidential Safes

Counter fronts and safe bodies fitted into cabinet work where panel thickness is constrained.

Combat Vehicles and Landing Craft

Armored personnel carriers combat vehicles submarines and landing craft where protection panels form part of the structure.

Armor Shields Helmets and Vests

Shields ballistic helmets and vest plates cut from the thin end of the thickness range.

Manufacturing

How It Is Made and Processed

  1. Steelmaking to the ballistic composition

  2. Hot rolling to the ordered plate thickness

  3. Quenching and tempering to the 500 or 550 hardness class

  4. Laser or water jet profiling of the panel outline

  5. Laser or water jet cutting of the fixing holes

  6. Bending on the lower class sections where the design calls for a formed profile

  7. Nature or painted surface finishing

  8. Marking packing and loading for export

Quality Control

Checks Before It Ships

  • Test report issued for the plate supplied
  • Hardness class confirmed for each ordered item within the 500-600 HB band
  • Thickness measured against the order before cutting
  • Panel outlines and hole centers checked against the drawing
  • Class marking checked so 500 and 550 panels are not mixed in packing
  • Surface finish inspected as nature or painted per the order
Customization

What We Can Change on Your Order

Comparison

Armor 500 550 Steel Plate Against the Alternatives

Armor 500 against Armor 550The 550 class raises ballistic performance at the same thickness and also raises the price while making folding welding and cutting harder.
Structural steel plateStructural steel may be only half the hardness of the 500-600 HB ballistic band so it cannot stand in at the same section.
One class across the whole structureMixing the two classes puts the cost and the forming difficulty only where the design needs the higher class.
Plate supplied uncutUncut plate leaves your shop with holes and profiles it cannot make, whereas panels leave here already cut on laser or water jet.
Use Guide

Specifying Handling and Welding Notes

  • Map the exposed zones first then assign Armor 550 to those and Armor 500 to the rest
  • Keep formed and welded sections in the lower class wherever the design permits
  • Send the panel drawing with hole centers so cutting is finished before dispatch
  • Mark class and panel number on the drawing so the two classes stay separated on site
  • Remember that performance at a given thickness rises with hardness when you fix panel sections
  • Ask for the test report with the order so the project file records both classes
Questions Buyers Ask

Armor 500 550 Steel Plate FAQ

What is the difference between Armor 500 and Armor 550?

They are two hardness classes of the same quenched and tempered ballistic plate. Higher hardness improves ballistic performance at the same thickness, costs more, and folds welds and cuts less easily.

Is this comparable to a Ramor 500 type plate?

Yes. Armor 500 550 steel plate is offered in the same way as a Ramor 500 type bulletproof steel plate and is also called ballistic steel plate or armor steel plate.

Can I order both classes on one order?

Yes. Both classes come from the same stock, so a single order can cover 500 class panels for one zone and 550 class panels for another.

What thickness is available?

Plate runs from 2mm to 100mm and armor steel sheet from 2.3mm to 100mm, cut to your customized panel size.

Who cuts the fixing holes?

We do. All fixing holes and cutting to size are performed on our laser machine or a water jet because hardened plate is difficult to cut in a general workshop.

What protection levels can be quoted?

FB4+, FB5, FB6, FB7, NIJ IIIA, NIJ III, NIJ IV, STANAG 4569 Level 1 and Level 2, and GA-3 to GA-6. Send the level named in the specification and the thickness will be confirmed against it.

Do you send a test report with the plate?

Yes. A test report is issued for the Armor 500 550 steel plate supplied and ships with the material.
