Stainless steel stretch die material

In order to reduce the possibility of adhesion when deepening, improve the quality of the workpiece and mold life, should use the formation of stainless steel with stainless steel material composition of the friction material, at the same time to consider the size of drawing parts and production volume.

1, the large size of the stainless steel parts, in the production batch is not large, in order to save material, should use cast iron HT300, QT600-2 as convex, die material, can also be used special wear-resistant cast iron.

2, the deep drawing of small and medium parts, the general use of copper-based alloy for mold materials, such as aluminum bronze, aluminum and iron bronze, phosphor bronze and so on.

3, the smaller size of the stainless steel parts deep drawing, the choice of cemented carbide YG8, YG15 for die, W18Cr4V for punch, proved to be deep in the concave corner and the wall is not easy to form a sticky tumor.

4, the use of silicon nitride ceramic mold for stainless steel drawing can get better results.
