Heat treatment cracking produced in the amount of carbon substance above 0.4%, Ms point within 330 ° C weathering rust steel plate. When the mass concentration of carbon is less than 0.4% and the Ms point is about 330℃, the weathering resistant rust steel plate does not cause heat treatment cracks.

Practical experience in processing and manufacturing has proved that the use of weather-resistant rust steel plates of wc=0.4% can prevent heat treatment cracks of parts.
(2) The effect of Al alloy elements on quenching cracking is intricate. When the element of aluminum alloy increases, the heat transfer of weather-resistant rust steel plate decreases, and the difference of change expands. At the same time, due to the expansion of the aluminum alloy composition, the martensite is strengthened, and the ground stress can not be relaxed according to the plastic deformation, so the heat treatment thermal stress is increased, and the trend of quenching crack is increased. As everyone knows, the improvement of the original composition of aluminum alloy has improved the cutting performance of the weather-resistant rust steel plate. If the heat treatment is used with a more relaxed surface quenching substance, the quenching cracking trend can be reduced.

In addition, some aluminum alloy elements such as vanadium and titanium have the effect of optimizing martensitic grain size, which can reduce the overtemperature trend of weather-resistant rust steel plates, and therefore reduce the trend of quenching cracking.
