A word of advice to those making drawing dies: stop using Cr12MoV for drawing dies. It will inevitably cause material adhesion and stringing\u2014there\u2019s no fixing it.<\/p>\n\n\n\n

 This afternoon, I received an inquiry from Mr. Liu regarding the drawing of 0.35mm-thick cold-rolled sheet. He is currently using Cr12MoV, and a small die core is sticking to the material, which increases friction. After polishing, the issue seems to resolve, but the die sticks again after 300 products. What is the cause?<\/p>\n\n\n\n

\u00a0The biggest concern with drawing dies is material sticking and stringing. Therefore, when selecting drawing dies, non-stick properties should be the top priority, followed by wear resistance. Cr12MoV is a high-carbon cold-work\u00a0tool steel<\/a><\/strong>\u00a0with a carbon content of 1.5%. It suffers from severe microstructural segregation and contains numerous microscopic cracks invisible to the naked eye. When this steel comes into contact with iron during the drawing process, material adhesion and stringing occur\u2014a problem that cannot be resolved; the only solution is to switch to a different tool steel<\/strong>.<\/p>\n\n\n\n

 The fact that the die sticks after just 300 products is sufficient proof that Cr12MoV is unsuitable for drawing dies. Having to polish a die after only 300 products\u2014especially one that was painstakingly machined\u2014makes production inefficient. While this die steel is cheap, the hassle it causes is unbearable. I also advise against applying a coating; it won\u2019t solve the problem and will only waste more money.<\/p>\n\n\n\n

 For die steel used in stretching iron parts, you must use at least 6077 wear-resistant steel.<\/p>\n\n\n\n

 6077 is an electroslag steel with high-quality smelting and low impurity content. Die stee<\/strong>l with low impurities achieves a good mirror finish, which is ideal for stretching dies; Additionally, as a six-sided forged steel (three forging and three drawing processes), it features excellent microstructural uniformity and minimal micro-cracks. This makes it less prone to sticking or stringing during drawing operations. With a hardness of HRC 60\u201363, it offers sufficient wear resistance and three times the fracture resistance of chromium steel, ensuring the die won\u2019t crack. There are already successful case studies of using 6077 wear-resistant steel for drawing dies with iron materials.<\/p>\n\n\n\n

Mr. Tan said that the 6077 wear-resistant steel he bought last time worked quite well. I use it to draw 0.7mm galvanized sheet metal into motor housings with a 30mm draw height. I\u2019ve already produced 3 million units, and I haven\u2019t received a single complaint from customers. Before, when I used DC53<\/a><\/strong>, the dies would start showing wire marks after just a few products, and I\u2019d get scolded by customers. Now, with 6077 wear-resistant steel, I can make 3 million products, and I\u2019m completely satisfied. I run a mold factory\u2014as long as customers don\u2019t complain, I\u2019m happy.<\/p>\n\n\n\n

\u00a0Mr. Liu\u2019s experience\u2014where the die stuck after just 300 products\u2014reminds me once again to advise everyone: don\u2019t use\u00a0Cr12MoV<\/a><\/strong>\u00a0for deep-drawing dies. It\u2019s a complete waste of money.<\/p>\n\n\n\n
