\u00a0I just received an inquiry from Mr. Chen regarding the stamping of 1.7mm-thick 65Mn hardened steel for C-type retaining rings with a material hardness of 45 HRC. Currently, they are using imported PM23 powdered high-speed steel<\/a><\/strong>\u00a0purchased from a certain online retailer for the lower die cutting edges, but the edges chip after producing only 9,000 pieces. He asked if I could recommend a better material.<\/p>\n\n\n\n

Stamping 1.7mm-thick hardened 65Mn steel with a hardness of 45 HRC involves stamping thick, hard material, which places extremely high demands on wear resistance and chipping resistance. However, they are already using PM23 powdered high-speed stee<\/strong>l, which costs several hundred yuan per kilogram\u2014a material of very high quality\u2014so it shouldn\u2019t be chipping this quickly.<\/p>\n\n\n\n

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

 PM23 is a high-speed steel<\/strong> produced using advanced powder metallurgy processes. It has no segregation or microcracks in its microstructure and a hardness of 64\u201366 HRC. It combines high hardness with high strength, offering excellent wear resistance and strength. However, it\u2019s now chipping after only 9,000 stamping cycles\u2014and this is happening on the cutting edge of the lower die, which is not prone to chipping, with large chunks breaking off. This has indeed left me somewhat puzzled.<\/p>\n\n\n\n

But since they purchased the die steel<\/strong> from a major supplier, we can\u2019t really object. All we can do is advise them to perform a tempering treatment to reduce the hardness to 60\u201364 HRC and try again.<\/p>\n\n\n\n

What surprises me even more is that you bought it from a major supplier\u2014a large company that should have after-sales service and the technical expertise to help you solve the problem. So why are you asking me, a lowly staff member? I really can\u2019t figure that out. Maybe it\u2019s the weekend, and he couldn\u2019t reach anyone else.<\/p>\n\n\n\n

After giving him the solution and things had calmed down, I suddenly realized that while the product is important, so is the service. The fact that your customers can reach you at any time is a form of assurance in itself.<\/p>\n\n\n\n

As consumers, what we fear most is being ignored when problems arise, or facing endless buck-passing. Taking responsibility is not only a duty but also a form of assurance. <\/p>\n\n\n\n
