"Mold steel S136 vs NAK80: Which material is better?"
Mold steels S136 and NAK80 are both high-quality die steels, and they have good performance in terms of hardness and toughness. However, which material is better depends on the specific application and needs.
First, let's take a look at the basic properties of these two materials.
S136 is a high-purity mold steel, which contains chromium, molybdenum, vanadium and other alloying elements in its chemical composition, which has good wear resistance and corrosion resistance. After heat treatment, the hardness of S136 can reach HRC50 or above, and it retains good toughness. Therefore, the S136 is suitable for making molds that require high precision and long life.
In contrast, NAK80 is a special heat-treated mold steel, which can reach hardness above HRC50 and has good mirror surface and corrosion resistance. NAK80 also has good toughness, which can maintain good toughness while maintaining high hardness. Therefore, NAK80 is suitable for making molds that require high precision and high corrosion resistance.
So, which material is better?
Actually, it is difficult to have a definitive answer to this question because both materials have their own advantages and disadvantages. S136 performs well in terms of wear resistance and corrosion resistance, and is suitable for molds that require high precision and long life. On the other hand, NAK80 has good performance in terms of mirror finish and corrosion resistance, and is suitable for molds that require high precision and high corrosion resistance.
Therefore, the choice of which material is better needs to be decided according to the specific application and needs. If you need to make molds that require high precision and long life, then S136 may be a better choice;If you need to make molds that require high precision and high corrosion resistance, then NAK80 may be more suitable for you.
In addition, other factors need to be considered, such as the cost of the material, the situation, the difficulty of processing, etc. These factors may have an impact on your choice.
In conclusion, there are many factors to consider when choosing which material is superior, including the application and needs, the basic characteristics of the material, the cost, and the situation. By considering these factors together, you can make a more informed choice.
