hardox 400 properties steel structural shapes

As the thickness and hardness of HARDOX 400 properties increase, the tendency to crack at the cutting edge increases. In order to prevent the HARDOX 400 properties from cutting cracks, preheating should be carried out before HARDOX 400 properties cutting. Special attention should be paid to preheating to make the entire HARDOX 400 properties interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole HARDOX 400 properties cannot be preheated, the partial preheating method can be used instead.

Mechanical properties of NM360 wear-resistant steel plate: after treatment, various performance samples are taken for testing. It can be seen that the new wear-resistant plate can obtain more uniform mechanical properties in a large size range, which not only has high strength and hardness, but also has high toughness. The HARDOX 400 properties, wear-resistant steel plate can also obtain different strength and toughness matching through reasonable allocation of carbon, silicon and manganese elements, which can meet different service conditions.

Oxygen is a harmful element in HARDOX 400 properties steel. With the increase of oxygen content, the strength of HARDOX 400 properties steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of HARDOX 400 properties steel.
