Armour Plates: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Grade and specification | Armor 400 / 500, Armor 500T, HSC 500T, MIL-A-46100 or MIL-A-12560, as your specification names; say which specification and revision applies. |
| Protection level | State the threat or protection class and the ballistic test standard your project cites; thickness and hardness are chosen to meet it. |
| Dimensions | Thickness × width × length in mm or inches; number of plates or total weight. |
| Condition | Quenched plate, not intended for further heat treatment; do not heat it above the mill’s limit. |
| Cutting | Waterjet cutting is preferred because it keeps the properties of the cut edge; laser and plasma are also suitable. |
| Welding and forming | Austenitic consumables are recommended; cold bending needs generous radii and safety measures. |

Description of the steel grades
Armor steels Plates are made with a novel direct quenching process. With this method not only a good blast and ballistic protection is attained, but also excellent flatness, surface quality and dimensional accuracy are getting.
Armor 400 steel is made to give defense against high anxiety caused by detonations and blasts.
Reading the text: “High anxiety caused by detonations and blasts” means high stress from detonations and blasts.
Armor 500 is the most appropriate choice, when protection is desired against kinetic energy projectiles i.e. ballistic presentation.
The number of the designation indicate the average Brinell hardness value 400 and 500 HBW, correspondingly.

Chemical composition
The chemical composition is stated in Table 2.
Table references: The text refers to Tables 1 to 5, which are not numbered on the page. Table 1 is the thickness tolerance table, Table 2 the chemical composition and Table 3 the typical mechanical properties, all at the end of the page. Tables 4 (materials testing) and 5 (minimum plate width for guard classes) are not on the page; ask for them if you need them.
Mechanical properties
Typical mechanical properties are presented in Table 3.
The plate must take suitable safety measures to protect themselves and no outsiders must be permissible in the area. The safest location is usually by the winding machine. The handling instructions of the steel supplier and safety instructions of the workshop must be adhered to in detail. New employees must receive appropriate training before they are allowed to process hardened steels.
Reading the text: “Winding machine” appears to mean the bending machine, and “the plate must take suitable safety measures to protect themselves” means the people working with the plate. Follow the mill’s handling and safety instructions.
Materials testing
Materials testing procedure is presented in Table 4.
Suggested minimum plate width of Armor 500 for different guard classes is presented in Table 5.
Heat treatment
Heat treatment is not recommended. If tempering procedure is needed, satisfy, contact technical customer service for further assistance.
Welding
Armor steels can be welded with common welding methods. Austenitic steel welding consumables are recommended. 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 Armor 500 steels by bending, the minimum bending radius of the upper tool has to be 8 times the thickness of the material. The corresponding bending radius for Armor 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
Armor 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
Armor steels can be machined using rigid hard metal tools and rigid equipment. Sufficient lubrication has to be provided and special concentration has to be paid to securing 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 treatment of hardened steels. Flanging is taxing due to the high strength and high flexural anxiety 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.

Reading the tolerance table: The upper tolerances are in mm. Heavy plate thicknesses of 6.00–30 mm are on the left; for sheets of 2.50–6.50 mm the tolerance depends on the width (up to 1200 mm, or 1201–1500 mm).

How the Six Ballistic Steel Pages Differ
The six pages cover armour plate to different mill brands and military specifications. Armor and HSC grades are quenched steels of about 400 to 560 HBW sold by thickness and hardness; the MIL specifications set hardness and ballistic approval for military use. The pages differ in the grade they describe and the data they give.

| ARMOR 500T | 480–540 HBW plate, 3–80 mm, Charpy-V 32 J at −40 °C, with chemistry and tolerances | Vehicles and buildings, with combined penetration and blast protection |
| ARMOR 500 | 490–560 HBW plate and cut lengths, 2–30 mm, with thickness and flatness tolerances | Ballistic protection of high hardness |
| MIL A 46100 | Military high-hardness armour, 477–534 BHN, quenched and tempered | Stopping high-velocity projectiles, such as sniper fire |
| MIL A12560 | Rolled homogeneous armour in four classes, typical 377–415 BHN | Combat vehicles, ammunition proof testing, landmine protection |
| HSC 500T | 480–540 HBW plate, 3–80 mm, Charpy-V 32 J at −40 °C, with chemistry and thickness tolerances | Vehicles, buildings and other protection applications |
