At present, D2 welded pipe mould and Cr12MoV welded pipe mould are many on the market. If we compare them, and see which one is better to use, how would you choose them?

First of all, we look at the material price. In terms of price, D2 is much more expensive than Cr12MoV. So for the same requirements of welded pipe mould, D2 material must be much more expensive. This is easy to understand, but the high price is not necessarily good for use.

Secondly, we can see the material properties. From the material suppliers and the websites of major material suppliers, D2 has better material properties than Cr12MoV, which is the reason why some die steels, and others must use D2. From this point of view, D2 welded pipe mould should be better

Finally, the difference between the two is not significant from the usage habits of design and master. Because both the design and operator are the same, the difference should be small. However, if a person is changed, the differentiation may come out. Because of the different technology, this can not be used as the criterion of evaluation.

In my opinion, D2 welded pipe mould should be better than Cr12MoV, because D2 corresponds to Cr12Mo1V1 in China, and the standard will be higher, and of course it should be better. Tell me which one you want.
