Introduction of Hardox 450 Plate
Hardox 450 is a Brinell hardness of 450HB wear-resistant steel plate with good cold bending. With high hardness, strength, and toughness, Hardox 450 steel plates can easily cope with harsh working environments.
Material handling and recycling are involved in many industrial fields. Especially in the field of mining and engineering, hard materials have put forward higher requirements for the wear-resistant components of equipment. While, Hardox 450 steel plates can provide excellent abrasion-resistance and durability for mechanical equipment.
Benefits of Hardox 450 plate
1. Excellent wear resistance
2. High strength and toughness
3. Excellent processing properties
4. Fatigue-resistant
Hardox 450 plate machining services




In the manufacturing of heavy mechanical equipment, the entire hardox 450 steel plate cannot be used directly. It must undergo precise processing such as cutting, bending, beveling, and drilling to form the required structural components or wear-resistant linings.
Due to high hardness and excellent wear resistance, Hardox 450 imposes stricter requirements on machining equipment and processing standards.
Plasma cutting technology maintains a dimensional accuracy within ±1mm, which is critical for minimizing errors during subsequent fabrication steps.
As illustrated in figure 2, a 40mm thick Hardox 450 plate has been successfully beveled and bent using a 4000-ton CNC press brake to produce a heavy-duty excavator lining. And arc curvature inspection (figure 3) guarantees adherence to specification and the client's requirements.
Furthermore, we also prefabricated precision parts (like figure 4) for use in mining structures and construction machinery. These high-performance components help minimize machine downtime and reduce long-term maintenance costs, offering enhanced durability in extreme working conditions.

Can you bend hardox 450?
+
-
Absolutely although Hardox 450 wear-resistant steel has a relatively high hardness, the difficulty of processing has increased significantly. However, years of manufacturing experience in mine steel structures and wear-resistant equipment enable us to accurately grasp client demands and control the inner diameter and angle of bending.
Can you drill hardox 450?
+
-
Yes, Hardox 450 can be drilled, but it requires proper tools. We recommend using high-speed alloy steel (HSS) drills or containing cobalt high-speed steel drills, which offer enhanced heat resistance and cutting performance. These tools ensure efficient and accurate drilling while minimizing tool wear.
