Armox® 370T – Composition, Properties and Uses

Armox 370T

In this blog post, we will explore the composition and properties of Armox 370T, its various uses, corrosion resistance, and other essential features.

What is Armox 370T?

Armox 370T is a specialized steel plate that offers high-level ballistic protection. This advanced material is designed to withstand heavy impacts and provide superior protection against bullet shots, bomb blasts, and other forms of violent attack.

Armox 370T Composition

Armox 370T is made up of hard martensitic steel, which is hardened and tempered to provide additional strength and durability. This steel has a low carbon content and is alloyed with chromium, molybdenum, and nickel, which provide extra stability, toughness, and corrosion resistance. This unique composition allows Armox 370T to withstand high-velocity impacts and retain its structural integrity even under extreme pressure.
