Upgrading from Hardox 400 to Hardox 450 enables you to increase service life or create lighter structures and, in some cases, do both. Because of Hardox steel’s workshop-friendly qualities, upgrading is usually a smooth process without any additional processing difficulties.

5 reasons to upgrade

1. Longer wear life — and longer uptime.

The additional 50 Brinell hardness gained by upgrading to Hardox 450 will increase the wear life. Case studies show that it is possible to achieve up to 50% greater wear life, and even more for some applications.

Examples of increases in wear life achieved by upgrading from Hardox 400 to Hardox 450 for different materials, according to WearCalc™

2. Lower lifetime cost

In these cost-conscious times, you’ll appreciate how longer wear life can lower your maintenance and equipment replacement costs, adding up to total savings.

3. Lower weight

Hardox 450 enables you to use thinner plates in your equipment and components. And thinner plates mean lower weight, more payload and increased profitability. Some of our customers have achieved weight reductions up to 15% after consideration of buckling, deflection and fatigue strength in their designs.

4. Improved dent resistance

Upgrading from Hardox 400 to Hardox 450 improves dent resistance as shown below. In this test, a weight of 300 kg (661 lbs) is dropped from a height of 2.8 m (9.2 ft) onto a test plate 600 x 600 mm (23.6 x 23.6 in).


5. Same tools and machines can be used

In the workshop, you can use the same tools and machines for Hardox 450 as for Hardox 400.

Hardox in the workshop

Hardox 450 is as fabrication friendly as Hardox 400. For example, it can be welded with all conventional arc welding methods intended for welding ordinary and high-strength steels. And all cutting methods — oxy-fuel, plasma, laser and abrasive water jet (AWJ) — can be used. When you upgrade, you can reduce plate thickness by at least 6% if you use the Hardox 400 bending force.
