If you buy a counterfeit 8566, not only will it fail to solve your mold chipping problem, but it will also lead you to misjudge the chip-resistant properties of 8566 die steel.
It’s like taking counterfeit medicine—it doesn’t cure your illness, yet you blame the medicine for being ineffective.
Mr. Cao has a lettering specialist who embosses characters on red copper. The punch has small characters with narrow borders. Currently, he’s using DC53 and Cr12MoV, but the characters tend to chip off easily. He wants to switch to 8566 anti-chipping steel, but his friend bought some online for 120 yuan per kilogram, which didn’t work well—it was just like regular die steel, lacking wear resistance and prone to chipping at the corners. He wasn’t sure what to do, so he called to ask me about the mold operating conditions and heat treatment process.
Many people who encounter mold chipping know to use 8566 anti-chipping steel because they are aware that 8566 offers excellent resistance to chipping and is the primary solution to this problem. It has been used in over a thousand cases across five stamping operating conditions, six major material types, and seven major industries.
However, they are unaware that 8566 mold steel is a proprietary anti-spalling steel developed exclusively by Yuhui. It is not a national grade but our company’s proprietary grade—it is our intellectual property and does not belong to the public domain. Years of experience led them to believe that 8566 must be a standard steel grade that can be purchased anywhere.
It was precisely this old-school experience that led him to fall into a trap. Because 8566 enjoys high market recognition, strong sales, and is specifically requested by customers, it has attracted “four types of copying” from competitors across the internet—not only “copied 8566” but also “shadow 8566.” It has even become a reference standard for certain major steel mills, creating an unprecedented and bizarre phenomenon in the industry. This peculiarity goes beyond the scope of their old-school experience.
“Four-Copy 8566” refers to competitors copying my product descriptions, my advertising slogans, my case studies, and even the “8566” mold steel grade itself—commonly known as “Four-Copy 8566.” They lure you in with low prices, and many people who are unaware of the truth end up falling into their trap.
To cure a disease, one must not only possess excellent medical skills and be able to accurately diagnose the cause and severity of the condition, but also prescribe the right medication to ensure a complete recovery. Pharmaceutical companies or herbalists alone cannot cure diseases.
Using 8566 die steel for punch chipping makes all the difference—it’s like night and day compared to the old methods. But if you don’t consult Wu Dejian, even using 8566 won’t solve the problem.
