Armox vs Hardox – What’s the Difference

Armox vs Hardox

Steel is critical in numerous industries today, from construction and agriculture to mining and transportation. In sectors where wear and tear are every days, high-strength steel is essential to ensure the durability and longevity of equipment. Two of the top brands in this category are Armox and Hardox. While many users may assume that the products are similar and interchangeably utilized, it is essential to understand their differences. This blog will comprehensively compare Armox vs Hardox, including their properties, applications, and strengths, to better understand which brand may be best for specific industry applications.

What is Armox?

Armox is a high-strength steel brand manufactured by SSAB, a Swedish firm that produces advanced high-strength steel products, including Quard, Ramor, and Domex. Armox is designed for security vehicles, bulletproof doors, bank counters, and other ballistic protection materials. This ultra-hard ballistic steel protects against armour-piercing rounds and is commonly utilized in the military, defence, and security industries.

What is Hardox?

Hardox is another high-strength steel brand produced by SSAB. It is commonly used for loading equipment, wear plates, and components for heavy tipper lorries, mining tippers, and construction machinery. Hardox is known for its impressive wear resistance, perfect for harsh working environments where equipment is continually exposed to abrasion and damage. Hardox comes in a broad range of toughness levels, ensuring that users can find the right product that fits their needs.

Difference Between Armox and Hardox

Even though Armox and Hardox have similar physical properties and are both high-strength sheets of steel, the primary difference is their intended use. Armox is designed for ballistic protection, while Hardox is used for abrasive and heavy wear environments. Each material is optimized to work well in its specified applications. However, the lighter Armox would be better for applications like armoured cars and bulletproof doors. At the same time, their thick Hardox plates would be better suited for tipping trailers, dump trucks, and excavation equipment.

What are the Physical Properties of Armox and Hardox?

Armox steel is available in thicknesses ranging from 4.00 mm to 80.00 mm and has a maximum hardness of 600HB. Its density ranges from 7.85 to 7.94 grams per cubic centimetre (g/cm3). Hardox, on the other hand, has a maximum hardness of 600HB, making it one of the most complex, most challenging, and wear-resistant steel brands that SAB produces. Hardox is available in thicknesses ranging from 0.7 mm to 160 mm and has a density range of 7.8-7.9 g/cm3.

Which is better?

Determining which is better between Armox and Hardox hinges on the application and needs of the user. If their working environment exposes them to harsh wear conditions, Hardox is the perfect option. In contrast, Armox steel is better suited for use where ballistic protection from armour-piercing rounds is necessary. However, if a user wants to balance wear resistance and ballistic protection strength, it is best to combine both materials.

Other Differences

  • Armox is a steel plate that is used in a variety of different applications.
  • Hardox is a steel plate that is used in a variety of different applications.
  • Armox is more expensive than Hardox.
  • Hardox is more wear-resistant than Armox.
  • Armox is more impact-resistant than Hardox.


Regarding high-strength steel brands, Armox and Hardox by SSAB are at the forefront of the industry. While both materials provide a high degree of strength and durability, they are designed and optimized for different user applications. By understanding the differences between Armox and Hardox, users can make informed choices about the right product needed for specific applications. Whether for armour plating or abrasive wear environments like construction and mining equipment, it’s essential to optimize the material for the particular needs of the work involved.
