6. Corrosion resistance
When some moulds such as plastic moulds are working, due to the presence of chlorine, fluorine and other elements in the plastics, HCI, HF and other strong corrosive gases are decomposed and precipitated after heating, which erode the surface of the mould cavity, increase its surface roughness and aggravate wear failure.
