Thermal cutting
XAR400耐磨钢板火焰切割加工
Preferably the flame-cutting process is used. For small product thicknesses, however, the plasma cutting process is used in the interest of minimum distortion.
Preheating is not normally necessary when flame-cutting thicknesses up to around 30 mm (1.181 in.). However, if the workpiece temperature is below + 5 °C (+ 41 °F), or the cut edges are to be cold-formed in the course of further processing, preheating to about 150 °C (302 °F) should be considered in the interest of cold cracking resistance.
XAR400耐磨钢板最好用等离子切割或者激光切割，然而，对于较厚的钢板，超过了等离子切割的厚度范围， 可以选用火焰切割切加工割。
XAR400耐磨钢板火焰切割加工厚度不大于30毫米的钢板时，一般情况下，不需要预热处理。 然而当被加工件温度低于+ 5 °C 时
，或者切割边在接下来的加工程序需要冷成形加工，则预热 150 °C 是需要考虑的以避免冷裂发生。
