I saw 6 pieces of 8566 diesteel<\/a><\/strong>\u00a0ordered by the hot forging factory in the workshop, and I remembered what the boss said. Since I used your 8566 die steel,<\/strong>\u00a0I can’t look at any other mold steel anymore. The mold has a long <\/p>\n\n\n\n

lifespan, requires less mold repair, makes workers easy, and my efficiency is high. From then on, his hot forging molds were made of 8566 die steel<\/strong>, and every time he came to buy, he would purchase 6 or 9 pieces. This time, he bought 6 pieces.<\/p>\n\n\n\n

 The main problems with hot forging molds are mold collapse and cracking, which are often caused by the poor heat resistance of the mold steel. When working at high temperatures, it is quickly annealed and loses its hardness, resulting in mold collapse and cracking. You always fix the mold and lower the surface. It’s not that mold steel is expensive or not, but rather that our efficiency cannot be achieved and we cannot produce goods. Even if mold steel is cheap, it is still expensive.<\/p>\n\n\n\n

The heat resistance of 8566 die\u00a0steel<\/strong>\u00a0is the same as that of high-speed steel SKH51, with a hardness of 58-60HRC and toughness four times that of SKH51. 8566 combines high heat resistance, high hardness, high toughness, and all three properties perfectly, which other mold steels do not possess.<\/p>\n\n\n\n

If you want high hardness and good thermal wear performance for your hot forging mold, and want to produce products with good smoothness, you can use 8566 <\/strong>die<\/strong> steel<\/strong>, especially high-temperature stainless steel hot forging, or multi-directional forging punches with longer forming times, standard nut hot forging dies, and molds with outer sleeve clamps. Mold steel with low hardness is prone to mold collapse and high hardness is prone to mold cracking. Therefore, you should use 8566 <\/strong>die<\/strong> steel<\/strong> with high hardness, high heat resistance, and high toughness.<\/p>\n\n\n\n

The hardness ranges from 58-60HRC, and hot forging die steel with such high hardness is extremely rare. It also has four times the toughness of SKH51, which is a rare performance. Anything that can achieve such high hardness is made of tungsten, which is not only expensive but also prone to mold cracking. Hot work mold steel without tungsten cannot achieve such high hardness, poor thermal wear performance, and short mold life. As Mr. Zhang mentioned, 8566 <\/strong>die<\/strong> steel<\/strong> is used for hot forging molds. As for hot forging 304 stainless steel, 8566 received a five-star rating, and the finished product has a good smoothness, similar to that of pipes.<\/p>\n\n\n\n

If your hot forging mold is prone to collapse and cracking, and your mold cost is sufficient, you can try 8566 <\/strong>die<\/strong> steel<\/strong> with high heat resistance, high hardness, and high toughness if you want a higher hardness of the mold to achieve more work with less mold repair.<\/p>\n\n\n\n
