1 large size stainless steel deep drawing stainless steel parts , not very large production volume, in order to save material , should use cast iron HT300, QT600-2 , etc., as convex and concave mold materials, may also be of special cast iron .
2 , small and medium size magnetic stainless steel sheet deep drawing parts , copper based alloys generally used as mold material, such as aluminum bronze, aluminum and iron bronze, phosphor bronze .
3 , for the smaller sized stainless steel deep drawing parts , the choice of carbide YG8, YG15 for the die , W18Cr4V as punch proved when drawing die radius and the inner wall of the aneurysm is not easy to form a bond .
4 , the use of silicon nitride ceramic molds for stainless steel deep drawing get better results , because the magnetism stainless steel is a typical inorganic non-metallic materials , and stainless steel vary widely , but it is very hard , strong wear resistance , not plastic deformation occurs , which can effectively overcome the adhesion of the die and the workpiece significantly improve die life.
