D2 steel and P20 steel are both commonly used die steels, but they differ in composition, properties, and application areas.<\/p>\n\n\n\n
D2 steel is a high-carbon, high-chromium alloy tool steel that contains about 1.5% carbon and 11.5% chromium, as well as some amounts of vanadium and molybdenum.<\/p>\n\n\n\n
It has excellent abrasion resistance, hardness and compressive strength, and the hardness can reach 58-62HRC after heat treatment. D2 steel is suitable for making high-precision and long-life cold work molds, cutting tools and measuring tools, as well as for stamping or forming dies, punching machines, forming rolls, knives, scissors, cutting machines, etc. D2 steel is machinable in the annealed state and has little to no deformation when properly hardened, and is slightly corrosion-resistant, but not as resistant to corrosion as stainless steel.<\/p>\n\n\n\n
P20 steel is a kind of pre-hardened plastic mold steel, which already has a certain hardness (usually between HRC30~42) when it leaves the factory, and is suitable for large and medium-sized precision molds. P20 steel contains about 0.28-0.4% carbon, 1.4-2% chromium, 0.3-0.55% molybdenum, and 0.05-0.1% nickel. It has good mechanical properties, processing properties and heat treatment properties, as well as certain corrosion resistance. P20 steel is often used in plastic molds and mold bases such as TV front shells, telephones, water dispensers, vacuum cleaners, etc.<\/p>\n\n\n\n
Conclusion: D2 Steel Vs. P20 Steel<\/h2>\n\n\n\n In general, D2 steel pays more attention to wear resistance and hardness, and is suitable for cold work molds that require high wear resistance and high hardness. P20 steel, on the other hand, is suitable for the manufacture of plastic molds, especially large and medium-sized precision molds, because of its pre-hardening characteristics, which can reduce the heat treatment time and shorten the construction period. Both have their own advantages, and the choice needs to be based on the specific application needs.<\/p>\n\n\n\n
FAQ<\/h2>\n\n\n\nWhat are the main differences in hardness between D2 Steel vs. P20 Steel?<\/h5>\n\n\n\n The main difference between D2 steel and P20 steel is their use and properties. D2 steel is a high-carbon, high-chromium tool steel with good wear resistance and hardness, which is suitable for making cutting tools and cold work molds. P20 steel is a kind of pre-hardened plastic mold steel, which has good mechanical properties and processing properties, and is suitable for making large and medium-sized precision plastic molds.<\/p>\n\n\n\n
Where is D2 steel used?<\/h5>\n\n\n\n D2 steel is widely used in cold work molds, cutting tools, stamping tools, and plastic molds.<\/p>\n\n\n\n
What does P20 pre-hardening do?<\/h5>\n\n\n\n The function of P20 pre-hardening is to improve the wear resistance and service life of the mold, and the pre-hardened steel can be directly used for mold processing, which saves the time of subsequent heat treatment and ensures the accuracy of mold manufacturing.<\/p>\n\n\n\n
Which is better for mold making, D2 Steel vs. P20 Steel?<\/h5>\n\n\n\n When comparing the mold making properties of D2 Steel vs. P20 Steel, P20 steel is generally more suitable because it has excellent machinability and toughness, making it ideal for producing injection molds.<\/p>\n","protected":false},"excerpt":{"rendered":"
