Due to the high frequency of use of guide posts and guide bush, and the special environment in which they are used, the material properties used in the production need to have good toughness and wear resistance. Let's learn about the common materials of mold parts and their characteristics.
45# carbon structural steel: Use 45# carbon structural steel or carbon tool steel, heat treatment, and quenching hardness HRC45 degrees.
SKD11: The general high requirement is to use SKD11 and H13 and other heat treatments to quench the hardness of about HRC51 degrees.
SUJ2: SUJ2 is Japanese standard-bearing steel, which is equivalent to my country's Gcr15. After quenching and tempering, it has high hardness, uniform structure, good wear resistance, and high contact fatigue performance. The service life is greatly improved, and it can be used as a material for mold accessories, and can also be used to manufacture wire drawing dies, cold heading dies, measuring tools, bearings, balls, etc. The steel has moderate cold working plasticity, average cutting performance, poor welding performance, high sensitivity to white spots, and temper brittleness.
GCr15: high carbon chromium bearing steel, after tempering and hardening, it has high hardness and wears resistance.
