\u00a0What type of die steel<\/a><\/strong> is used for hot-forged nuts? Hot-forging die manufacturers all use Yuhui 8566 die steel<\/a><\/strong>. We just purchased another 10 pieces.<\/p>\n\n\n\n

Our client specializes in hot-forged nuts. Since nuts are standard parts produced in large quantities, they require high thermal wear resistance and heat resistance. Previously, they used tungsten carbide dies. Tungsten carbide dies offer high hardness and excellent wear resistance, but after the price of tungsten carbide dies rose from over 800 yuan per die to over 3,000 yuan, the customer simply gave up and stopped negotiating with us.<\/p>\n\n\n\n

 However, hot forging dies have very high requirements for heat resistance, thermal stability, and thermal wear resistance. We still need to select die steel<\/strong> with high heat resistance, high hardness, and high toughness. Yet, there are very few hot-forging die steels on the market that offer high hardness, high toughness, and high heat resistance.<\/p>\n\n\n\n

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

\u00a0The heat resistance of 8566 is comparable to that of high-speed steel<\/a><\/strong>\u00a0SKH-51, with a hardness of 58\u201360 HRC. Its toughness is four times that of SKH-51. 8566 perfectly balances high heat resistance, high hardness, and high toughness\u2014a combination of properties that other mold steels lack.<\/p>\n\n\n\n

 Because 8566 <\/strong>die<\/strong> steel<\/strong> offers high hardness and excellent heat resistance, it does not anneal or lose hardness when operating at high temperatures. Combined with its high hardness, this ensures resistance to thermal wear. Furthermore, its high toughness prevents cracking under rapid cooling and heating cycles at high temperatures. When used in hot forging dies for nuts, it delivers excellent performance and a long service life.<\/p>\n\n\n\n

 If your hot forging dies currently use low-hardness die steel <\/strong>with poor thermal wear resistance, or if you\u2019re using tungsten carbide (which is prone to cracking and extremely costly), you may want to consider trying 8566 die stee<\/strong>l.<\/p>\n\n\n\n

 Regarding hot forging of 304 stainless steel, Mr. Zhang gave 8566 a five-star review, noting that the product has excellent surface finish and that the finished parts look just like those made from tubing.<\/p>\n\n\n\n
