P20 and 718 are two types of mold steels commonly used in the production of injection molds for plastic parts. While both steels are suitable for many applications, there are some differences between them in terms of their properties and performance.
P20 is a low-carbon, low-alloy steel that is easy to machine and has good toughness and wear resistance. It is commonly used in the production of molds for low-volume production runs or prototyping. P20 is less expensive than 718 and can be used for smaller, less complex molds.
On the other hand, 718 is a high-grade, high-performance steel that is more expensive than P20. It has excellent dimensional stability, high hardness, and good resistance to corrosion and heat. It is commonly used in the production of molds for high-volume production runs or complex parts that require tight tolerances and precise surface finishes.
Here are some specific differences between P20 and 718:
1. Hardness: 718 has a higher hardness than P20, which makes it better suited for molds that require high precision and wear resistance.
2. Corrosion resistance: 718 has better corrosion resistance than P20, which makes it a better choice for molds that will be used in harsh or corrosive environments.
3. Machinability: P20 is easier to machine than 718, which makes it a more cost-effective option for smaller, less complex molds.
4. Cost: P20 is less expensive than 718, which makes it a more economical choice for low-volume production runs or prototyping.
In summary, P20 and 718 are both suitable materials for injection molds, but the choice between them depends on the specific requirements of the mold and the production process. P20 is a more affordable option for smaller, less complex molds, while 718 is a higher-grade steel that offers superior performance for larger, more complex molds.
