There are pre embedded molds that will not crack. You can use 8566 die steel with high heat resistance, high hardness, and high toughness\u3002<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The heat resistance of 8566 die steel is the same as that of high-speed steel SKH51, with a hardness of 58-60HRC and toughness four times that of SKH51. 8566 die steel softens the three aspects of high heat resistance, high hardness, and high toughness perfectly, while other die steels cannot achieve such high hardness and maintain such high toughness. Mr. Chen said that the hexagonal nuts made of hot forged iron, 8566, have been used in 40000 pieces and are quite useful.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"663\" height=\"1024\" src=\"https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/02\/K\u6797\u5148\u751f-8566\u70ed\u953b\u87ba\u6bcd-\u5174\u53d1\u673a\u68b0\uff0c\u70ed\u953b\u94c1\u6599\u7684\u516d\u89d2\u87ba\u6bcd\uff0c8566\u6253\u4e864\u4e07\u4ef6-663x1024.jpg\" alt=\"\" class=\"wp-image-144\" srcset=\"https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/02\/K\u6797\u5148\u751f-8566\u70ed\u953b\u87ba\u6bcd-\u5174\u53d1\u673a\u68b0\uff0c\u70ed\u953b\u94c1\u6599\u7684\u516d\u89d2\u87ba\u6bcd\uff0c8566\u6253\u4e864\u4e07\u4ef6-663x1024.jpg 663w, https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/02\/K\u6797\u5148\u751f-8566\u70ed\u953b\u87ba\u6bcd-\u5174\u53d1\u673a\u68b0\uff0c\u70ed\u953b\u94c1\u6599\u7684\u516d\u89d2\u87ba\u6bcd\uff0c8566\u6253\u4e864\u4e07\u4ef6-194x300.jpg 194w, https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/02\/K\u6797\u5148\u751f-8566\u70ed\u953b\u87ba\u6bcd-\u5174\u53d1\u673a\u68b0\uff0c\u70ed\u953b\u94c1\u6599\u7684\u516d\u89d2\u87ba\u6bcd\uff0c8566\u6253\u4e864\u4e07\u4ef6.jpg 750w\" sizes=\"auto, (max-width: 663px) 100vw, 663px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Mr. Hu&#8217;s red nut mold is now prone to cracking with tungsten steel molds, and the cost is too high.
