Armox® 370 – Composition, Properties and Uses
This blog post will delve deeper into the composition, mechanical and physical properties, uses, and other essential information about Armox 370.
What is Armour 370?
Armox 370 is a high-grade steel plate known for its exceptional strength, durability, and resilience to impact. It is designed to protect against ballistic threats, explosions, and other high-energy impacts. This steel plate is widely used in military vehicles, armoured cars, and other defence industries.
Armox 370 Composition:
Armox 370 is a low-alloy steel plate primarily composed of carbon, silicon, manganese, and molybdenum. It also contains traces of other elements, such as chromium, vanadium, and nickel. The chemical composition of Armox 370 is carefully designed to deliver optimal protection, strength, and ductility. The steel plate has a maximum hardness of 444 HBW (Brinell Hardness) and is tempered at low temperatures to ensure that it retains its exceptional properties.

Armox 370 Uses:
Armox 370 is mainly used in the defence industry to provide ballistic and blast protection to military vehicles, armoured cars, and other structures requiring this protection level. It is also used to construct high-security buildings like banks, embassies, and government buildings. Armox 370 is an excellent choice for protecting critical infrastructure, especially in high-risk areas.
Armox 370 Corrosion Resistance:
Armox 370 also exhibits excellent corrosion resistance thanks to its composition, which includes chromium, nickel, and molybdenum. This makes the steel plate suitable for use in harsh environmental conditions with high moisture and salt content, reducing the need for frequent maintenance.
Armox 370 Heat Treatment and Machining:
Armox 370 undergoes a controlled heating and cooling process known as tempering to achieve its exceptional properties. This can either be done through low-temperature tempering or elevated-temperature tempering, depending on the desired properties. Armox 370 can be machined using conventional methods and has a relatively low cutting force. However, it is essential to use appropriate tools and machining parameters to prevent damage to the steel plate.
Armox 370 Welding:
Armox 370 can be welded using conventional methods such as MIG/MAG and TIG welding. However, it is essential to follow specific welding procedures to prevent damage to the steel plate’s properties. Welding Armox 370 requires specialized expertise and tools due to its unique characteristics.
Conclusion:
Armox 370 is a high-end steel plate designed to deliver optimal protection and strength against high-energy impacts, ballistic threats, and other threats. Its exceptional mechanical and physical properties make it an ideal choice for the defence industry, critical infrastructure protection, and other applications requiring this protection level. As such, Armox 370 has become the go-to solution for many defence contractors and infrastructure providers globally.
