HARDOX400耐磨板耐磨板切割折弯加工焊接注意事项

HARDOX400具有HBW400的硬度,是一种全能耐磨钢,由于其韧性高,折弯性极佳,焊接性能也优良,这种钢可以用于中度磨损的结构。

 Hardox400 has the hardness of hbw400. It is a kind of all-round wear-resistant steel. Due to its high toughness, excellent bending property and excellent welding performance, this kind of steel can be used for structures with moderate wear.

根据生产工艺不同,分为薄板和厚板,薄板厚度在2.0mm-8.0mm,硬度范围在HBW370-HBW430之间,板内部硬度略低于表面硬度,但是因为采取整体淬火,其中心硬度是保证的表面硬度的90%。由此可以看出悍达400的整体均匀度非常的不错,也代表了其加工性能优秀。

According to the different production process, it is divided into thin plate and thick plate. The thickness of thin plate is 2.0 mm-8.0 mm, and the hardness range is hbw370-hbw430. The internal hardness of the plate is slightly lower than the surface hardness, but because of the overall quenching, the central hardness is 90% of the guaranteed surface hardness. From this we can see that the overall uniformity of humda 400 is very good, which also represents its excellent processing performance.

厚板的厚度在4.0mm-130mm,同样硬度在HBW370-HBW4300之间。薄板和厚板的典型屈服强度都是1100MPA。HARDOX400耐磨板的冲击特性,在夏比冲击测试v型10*10mm试样纵向测试典型冲击能量,达到45J/-40摄氏度。这个数字标明了在低温环境下,HARDOX400可以保持良好的机械性能。

The thickness of thick plate is 4.0 mm-130 mm, and the hardness is also between hbw370-hbw4300. The typical yield strength of thin and thick plates is 1100mpa. Hardox400 impact characteristics, Charpy impact test V-type 10 * 10mm specimen longitudinal test typical impact energy, up to 45j / - 40 ℃. This number indicates that Hardox400 can maintain good mechanical properties at low temperature.

HARDOX400耐磨板可以使用普通火焰切割,等离子切割激光切割和水刀切割。不过火焰切割耐磨板会造成切口周围一定范围内耐磨板的硬度下降,所以如果对切口硬度要求高的场合,尽量使用等离子切割。

Hardox400 wear resistant plate can be cut by ordinary flame, plasma, laser and water jet. However, flame cutting wear-resistant plate will cause a certain range of wear-resistant plate around the incision hardness decline, so if the incision hardness requirements are high, try to use plasma cutting.

等离子切割耐磨板是一种性价比最高的切割方式,等离子切割耐磨板时,注意使用冷却水进行冷却,可以较好的降低高温对耐磨板硬度降低的影响。水刀切割耐磨板是最优秀的方式,当然要能够接受水刀切割的昂贵价格。

Plasma cutting wear-resistant plate is a cutting method with the highest cost performance. When plasma cutting wear-resistant plate, attention should be paid to the use of cooling water for cooling, which can better reduce the impact of high temperature on the hardness reduction of wear-resistant plate. Water knife cutting wear plate is the best way, of course, to be able to accept the high price of water knife cutting.

折弯卷圆耐磨板的时候,尽量不要使用预热的方法来加工。因为HARDOX400本身的硬度相较于HARDOX500低了不少,所以加工起来还不是特别困难。但是如果折弯的角度较大,可以预先做倒角处理,防止耐磨板开裂。卷圆时候如果曲度过大,或者设备卷不动,可以适当的预热处理。

When bending wear-resistant plate, try not to use preheating method to process. Because the hardness of Hardox400 is much lower than that of hardox500, it is not particularly difficult to process. However, if the bending angle is large, chamfering can be done in advance to prevent the wear plate from cracking. If the curvature is too large, or the equipment can not roll, it can be preheated properly.
