However, after researching extensively online, he discovered that 8566 chipping-resistant steel is a proprietary product of Yuhui. So he asked these blade manufacturers, and every single one told him they were using Yuhui\u2019s 8566, shipped from Guangdong, with prices varying widely. He felt very uneasy about this. To put his mind at ease, he kept searching online until he found my video. He then called me to ask if there were any blade manufacturers who had purchased my 8566 to make these blades\u2014so he could simply buy the 8566 blades from that manufacturer.<\/p>\n\n\n\n As a customer, spending money isn\u2019t the issue; the biggest fear is buying blades that don\u2019t perform well\u2014wasting money on something that doesn\u2019t work. That\u2019s the most heartbreaking part. After receiving this message, I felt quite disheartened. I never expected that 8566 chipping-resistant steel\u2014which used to be copied and counterfeited only in the mold industry\u2014would now be facing chipping issues in our tooling and cutting tool industries as well, requiring the use of 8566 chipping-resistant steel, and that it\u2019s already being copied.<\/p>\n\n\n\n The materials used for these shredder blades are generally very inexpensive. Inferior blades are made from 45 steel, with the cutting edge subjected to high-frequency quenching. The advantage is that they\u2019re cheap, but the cutting edge lacks sharpness. Slightly better quality blades use H13, with a hardness of 50\u201354 HRC; it offers better wear resistance than 45 steel while maintaining toughness. For higher hardness, manufacturers might use Cr12MoV or DC53<\/strong>; while these meet the hardness requirements, they are prone to chipping and are not practical. The ideal blade material combines high hardness with good toughness, ensuring a sharp cutting edge without chipping.<\/p>\n\n\n\n The chipping resistance of 8566 anti-chipping steel is four times that of SKH-9 high-speed steel<\/strong> and twice that of D2, with a hardness of 58\u201360 HRC. It is primarily designed to address the chipping issues that high-hardness die steels such as D2, DC53, and SKH-9 cannot resolve. The properties of 8566 make it highly suitable for crusher blades, offering both high hardness and excellent chipping resistance\u2014though the price is too high. As things stand, people have been consulting me about this for several years, but so far, no blade manufacturer has actually put it into practice.<\/p>\n\n\n\n Based on Mr. Lin\u2019s concerns and his inquiry, I\u2019ve identified a business opportunity. The objective need to address blade chipping exists, and 8566\u2019s superior chip resistance makes it well-suited for blade applications. Customers have this pain point, and since our product offers this performance, this application scenario represents a new field of application for 8566\u2014and a new market demand.<\/p>\n\n\n\n It\u2019s true that every industry is highly competitive these days, but everyone is striving to move up the value chain. Users want blades with excellent performance and a long service life\u2014not cheap blades that chip easily. If you produce the same products as every other blade manufacturer, you won\u2019t be competitive, and you won\u2019t hold any standing with customers. I hope that in the future, a blade manufacturer will be willing to take the first step\u2014using 8566 chipping-resistant steel to help your customers solve blade chipping and sharpness issues\u2014and claim the first slice of the market.<\/p>\n\n\n\n![\"\"](\"https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/09\/blog-312-\u7c89\u788e\u673a\u5200\u7247.jpg\")
