Wire drawing in deep-drawing dies is an extremely common phenomenon\u2014and even a major pain point in the deep-drawing industry. During my 296th live stream, several viewers reported issues with wire drawing in their deep-drawing dies. Three of these cases left a particularly strong impression on me; they all asked what type of die steel<\/a><\/strong>\u00a0to use to prevent wire drawing.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The first was drawing 3-thick cold-rolled sheet to produce automotive control arm parts. They were currently using Cr12MoV<\/strong>\u00a0with TD heat treatment, but stringing occurred after producing only a few parts. This was due to incorrect material selection.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The second viewer was drawing 0.7-thick DC04 material and asked which die steel to use to minimize stringing.<\/p>\n\n\n\n

 For these two viewers, I recommended using wear-resistant steel 6077. I have a client who deep-draws 0.7-thick galvanized sheet metal for motor housings, with a draw depth of 30 mm. When using DC53, the die would develop wire marks after producing only a small number of parts, leading to frequent customer complaints.<\/p>\n\n\n\n

 After he contacted me, I recommended he use wear-resistant steel 6077. He reported that a die made from 6077 produced 3 million parts before needing replacement\u2014I was very satisfied with that result. Wear-resistant steel 6077<\/strong> will also develop wire marks after a certain number of products, but it doesn\u2019t happen very often. I just polish it, and it\u2019s ready to use again\u2014no complaints from the customer. Wear-resistant steel 6077 isn\u2019t expensive, but it performs much better than DC53; a single die produced 3 million products without being scrapped. As a die manufacturer, I\u2019m happy as long as the customer doesn\u2019t complain.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The first two users mentioned here are drawing steel, and even with Cr12MoV plus TD treatment, they still experience stringing. I think wear-resistant steel 6077 is definitely worth a try. If you\u2019re willing to add a coating, the results will be even better.<\/p>\n\n\n\n

The third user is drawing 0.6-thick 304 stainless steel. He\u2019s already using M35 high-speed steel with a hardness of 65 HRC, but it still tends to string.<\/p>\n\n\n\n

This is likely because the M35 you purchased was of poor smelting quality, with too many microcracks in its microstructure, leading to mold sticking and stringing. There are two solutions: either apply a coating to the M35 or switch to\u00a0PM23 powdered high-speed steel<\/a><\/strong>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

 Based on these users\u2019 questions, I believe that stringing in drawing dies may be a common industry pain point\u2014a widespread phenomenon.<\/p>\n\n\n\n

I think that when selecting steel for drawing dies, smelting quality should be a top priority. Steel free of segregation and microcracks in its microstructure is the fundamental and effective way to prevent stringing in drawing dies.<\/p>\n\n\n\n

 For drawing dies used with iron materials, you should use at least wear-resistant steel 6077 or non-stick 8503 die steel. These can be used for direct drawing without the need for surface coating. Once they\u2019ve reached a certain production volume and show wear, simply polish them, and they can be reused\u2014this is a low-cost material option. If you\u2019re willing to add a coating, it will yield twice the result with half the effort.<\/p>\n\n\n\n

Second, if your budget allows and the die is not too large or material-intensive, you can use powdered high-speed steel or tungsten carbide\u2014these work very well.<\/p>\n\n\n\n

 It\u2019s important to note that Cr12MoV should be used with caution in drawing dies\u2014or better yet, avoided entirely\u2014as dealing with wire drawing defects caused by it is very troublesome.<\/p>\n\n\n\n
