High property of HARDOX400 steel plate wear-resistant structural

HARDOX 400 steel plate is a multi-purpose wear-resistant steel with high toughness, high bending and high weldability. HARDOX 400 steel plate is a kind of all-round wear-resistant steel. Due to its high toughness, good bending and weldability, HARDOX 400 steel plate can be used for medium wear structure.

HARDOX 400 steel plate, also known as wear plate, has a longer service life than standard mild steel. The most common hardness grades are 400 and 500. The combination of hardness, strength and toughness of HARDOX 400 steel plate enables it to withstand extreme wear. Despite its high hardness, HARDOX 400 steel plate can still be used for cutting, welding, grinding and drilling.
