What are Armour Plates?

Despite its high density, steel is an excellent all-around Armour material due to its high toughness, quick availability, low cost, castability, and weldability. It is interesting to note that Armour steels are stronger as well as harder and more fracture-tough than regular steel. Their main purpose during combat is to protect objects from being damaged by pressure or projectiles. Armored vehicles are usually made using these steels as hot rolled plates.


There are four major categories in which to place steel Armour. These categories include rolled homogenous Armour (RHA), high hardness Armour (HHA), variable hardness steel Armour (VHSA), and perforated Armour. RHA steels are typically regarded as a benchmark material out of these four categories. For light Armoured vehicles, RHA steel has historically been thought of as the standard Armour material. It is a premium alloy steel that has been rolled out before being heat treated to give it the best possible balance of strength and toughness.


Armour steel is a common material for Armoured vehicles because of its key characteristics, which include toughness, hardness, excellent fatigue strength, ease of production and joining, and relative affordability. The crucial criterion for this steel is that it must preserve the integrity of the structure even when hit by outclassing artillery projectiles at subzero temperatures. As a result, this steel must possess low-temperature impact strength. Other crucial factors for the Armor Steel Plates are their ability to be produced in a range of shapes, be easily weldable, and be receptive to contemporary fabrication and building procedures.


Properties Armour Plates

In its simplest form, Armour steel is a high strength, low alloy structural steel that has been specially treated to provide very high resistance to penetration. The heat treatment, typically the Thermo mechanical treatment, is what gives steel this characteristic. It is generally known that increasing the intensity of steel’s texture, which can be accomplished through thermo-mechanical processing, can increase the material’s resistance to penetration. With increased material hardness, Armour becomes more effective overall. However, particularly hard Armour tends to be brittle and break when struck.


Chemical Composition of Armour Plates

The effects of the steel’s chemical composition, austenitization and tempering temperatures, and grain size on its mechanical characteristics and, consequently, on how well it performs in ballistics, are well recognized. It is also known that by adjusting the chemical composition and the heat treatment conditions, martensitic steels’ mechanical characteristics and ballistic performance may be improved.


Applications of Armour Plates

To boost levels of protection against the hostile environments and circumstances they confront, the military, defense, and security industries use Armour Plates steel globally. The extreme hardness and strength of Armour plate steel, which is used primarily in the military, offer significant levels of protection against blast and ballistics.
