Hardox 450 vs AR450 – What’s the Difference

Hardox 450 vs AR450

When choosing the best steel for your projects, many options exist. Among these options are Hardox 450 and AR450, two materials frequently mentioned in the steel industry. Although they seem identical, their differences can impact your project’s effectiveness. This blog post will explore the difference between Hardox 450 and AR450.

Difference Between Hardox 450 and AR450

Chemical Composition

The primary difference between the two materials is their chemical composition. Hardox 450 is an abrasion-resistant steel with high amounts of chromium, molybdenum, and nickel. On the other hand, AR450 is a type of wear-resistant steel that has a high carbon content. As a result of their different chemical compositions, they have unique properties that make them suitable for different applications.

Hardness and Durability

Hardox 450 is known for its superior hardness and durability. It has a maximum hardness of 450 Brinell, hence its name. This type of steel is commonly used in mining, construction, and earthmoving equipment due to its resistance to wear and tear in harsh environments. In contrast, AR450 has a lower maximum hardness but is still considered highly durable. It is suitable for applications where moderate abrasion resistance is required.

Impact Resistance

Another area where the two materials differ is their impact resistance. Hardox 450 has good impact resistance due to its stricter core material. It is less likely to crack or break when subjected to heavy impact. AR450, while still having good impact resistance, may not be as effective as Hardox 450 regarding heavy implications.


While both materials are high-quality options, Hardox 450 tends to be more expensive than AR450 due to its superior properties. The cost can vary depending on the supplier and the material being ordered. AR450 is a more affordable option that provides reliable performance and durability.


When choosing between Hardox 450 and AR450, it is essential to consider the application’s requirements. Hardox 450 is ideal for high-wear applications like mining, construction, and earthmoving industries. AR450 is suitable for moderate-wear applications, such as transportation equipment, farm machinery, and manufacturing equipment. Choosing the best material for your application will ensure optimal performance, durability, and cost-effectiveness.


In conclusion, Hardox 450 and AR450 are both high-quality steel materials that offer durability and resistance to wear and tear. While they share many similarities, the differences in their chemical compositions, hardness, impact resistance, and cost make them suitable for different applications. Understanding these key differences will help you choose the best material for your project, ensuring optimal performance and cost-effectiveness.
