Hardox400 wear-resistant plate is a kind of heat-treated steel plate, and most of the wear-resistant steel plates on the market, when heated to a certain temperature, about 300 degrees above, the hardness will drop rapidly. Therefore, when cutting, the wear-resistant plate should be cold cut as far as possible, otherwise the hardness will decrease.
Hardox400 wear-resistant plate belongs to heat-treated quenched and tempered steel plate, so plasma cutting or other cutting methods have been used in cutting. Flame cutting is to use high temperature oxygen to cut the wear-resistant plate, so flame cutting processing will produce heat affected zone on the wear-resistant plate. Now the Hardox400 wear-resistant plate is still using flame cutting. Generally, the hardness requirement of the cutting place is not high, and the problem of hardness decline can be ignored. Because the flame cutting can be co edge cutting, saving materials.
Cutting costs are also relatively low. From an empirical point of view, Hardox400 wear-resistant plate processing has no heat affected zone, only water knife cutting and wire cutting processing, but in fact because of the price reason, the use of these two kinds of cutting wear-resistant plate is not much. Laser cutting processing of harda wear-resistant plate takes the second place, plasma cutting heat affected zone is also relatively small, but because the cutting incision is inclined, so it will waste some materials.
If the thickness is greater than 50 mm or the processing conditions are limited, this problem should be considered in the design of wear-resistant plate, and the heat affected zone can also be removed by processing. In addition, if the wear-resistant plate is less than 40mm, the flame cutting should be avoided. On the one hand, it will bring thermal deformation and waste the wear-resistant plate, especially for the wear-resistant plate with thickness less than 10mm, the impact of flame cutting will be very large.
