<\/figure>\n\n\n\nPM60 is a high-speed<\/strong> steel produced by powder metallurgy, with a carbon C content of 2.3%, cobalt Co content of 10.8%, and a hardness of 67-69HRC. These visible indicators are similar to everyone, but the key to determining the durability of mold steel is the quality of smelting, internal structure, microstructure, heat treatment process, and the comprehensive performance presented. This is the key to testing the technology.<\/p>\n\n\n\n The blades made by Yuhui PM60 can last for more than half a year, while the cheap PM60 will collapse within a few days. The poor quality lies in the smelting quality, internal structure, organizational state, and heat treatment process, which is also where they cut corners and pass off inferior materials as good.<\/p>\n\n\n\n Yuhui PM60 is processed through advanced powder metallurgy technology, resulting in a fine and uniform carbide structure with a dispersed distribution, no segregation, and no directionality in the steel. No matter how it is processed, it does not affect its use. The heat treatment is carried out using Wu’s proprietary technology, which is specially made in a furnace to ensure perfect steel performance. Therefore, it can not only guarantee high hardness but also high strength, and the cutting edge will not collapse. It can be used for more than half a year, which is a performance that inferior PM60 does not possess.<\/p>\n\n\n\n However, PM60, which sells inferior materials as good, although its alloy composition meets the standard, has poor smelting quality and segregation nodules in the steel, resulting in a sharp decline in its performance. In addition, the heat treatment process is insufficient, so it only has high hardness without high strength, and it will collapse under external impact. It is now used for a few days, which also proves this point.<\/p>\n\n\n\n The structure of mold steel cannot be seen with the naked eye, and ordinary people cannot distinguish it at all. It can only be compared during use.<\/p>\n\n\n\n Comparison generates value, but many of our users do not understand mold steel, smelting quality, or mold working conditions. They only compare prices and think that cheap is good. However, if the mold is not smooth, it can harm people. After being deceived, they want to kill people. Only then do they realize, but it is too late.<\/p>\n\n\n\n
