201 stainless steel prices

201 stainless steel tensile mold material how to choose to reduce 201 stainless steel showing the possibility of cohesion, improve the quality of the workpiece and die life, should be used with stainless steel to form a friction material of different metallic materials, taking into account the drawing parts Size and production batch size.

1, the drawing of large stainless steel parts, production lot is not very large, for the throttling material, should use cast iron HT300, QT600-2 as convex, die material, but also can be used special wear-resistant cast iron.

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

3, the smaller size of stainless steel parts drawing, the choice of cemented carbide YG8, YG15 for the die, W18Cr4V for the punch, the practice proved that the die at the fillet and the inner wall is not easy to form a bond.

4, the use of silicon nitride ceramic mold for drawing 201 stainless steel can get better results, because silicon nitride is a typical inorganic non-metallic materials, and stainless steel is very different, but it is very high hardnes

s, abrasion resistance , Plastic deformation will not occur, can effectively overcome the adhesion of the mold and the workpiece, significantly improve die life.
