Hardox steel is known for its exceptional hardness, toughness and abrasion resistance – and the Hardox 400 plate is no exception. This all-round, wear-resistant steel has a nominal hardness of 400 HBW, with a toughness, bendability and weldability that makes it suitable for structures and components subject to moderate wear.

Delivery status:
The delivery status is quenched. Open slab without primer, for cutting or thermal cutting edge. The surface of the medium and heavy plate is pretreated with red anti-rust paint, and the edges are cut or hot cut. Hardness range 370-430 (HBW).
HARDOX400 wear-resistant steel plate heat treatment:
Hardox 400 obtains its mechanical properties by means of quenching (if necessary, tempering continues after quenching). However, after the steel plate is used or the preheating temperature exceeds 250°C, the performance will not be guaranteed to be the same as the performance specified in the delivery conditions. Hardox 400 does not require any further heat treatment.
HARDOX400 wear-resistant steel plate thermal processing:
In the process of welding, cutting, grinding, and other processing steel plates, appropriate precautions to protect health and safety need to be taken. Especially when sanding, due to the anti-rust paint on the surface of the steel plate, dust with high concentration of fine particles may be generated. If necessary, we will provide more detailed related information.
