S45C has been pre hardened to 285-330HB (30-36HRC) and can be directly used for mold processing, with good dimensional stability. Pre hardened steel can meet general usage requirements.
Excessive silicon content can also increase the brittleness and cracking tendency of S45C, so the silicon content needs to be appropriately controlled. The structural design of S45C should be as simple and smooth as possible to avoid excessive complexity. S45C has excellent corrosion resistance and oxidation resistance, and can be used at room temperature.
Suitable materials should be selected based on the specific usage environment and requirements. S45C containing high alloy elements usually has good corrosion resistance. The characteristics of S45C: no heat treatment required, excellent polishing performance, good cutting ability, and good etching resistance; Vacuum degassing and refining treatment for steel purity; Spheroidizing annealing and softening treatment, with good cutting performance; The strengthening element vanadium and molybdenum are specially added, resulting in extremely excellent wear resistance.
Toughness reflects the plastic deformation ability of S45C. A good toughness S45C can withstand significant plastic deformation and avoid cracking or deformation when subjected to external forces. The hardness of S45C ranges from 28.66HRC to 36.66HRC, and the hardness after heat treatment can reach 50.65HRC.
In summary, S45C is widely used in the manufacturing of high demand S45C and tools, such as molds, injection molds, die-casting molds, extrusion molds, extrusion heads, etc. S45C is widely used in the manufacturing of injection molds, extrusion molds, die-casting molds, extrusion heads, cutting tools, and other industrial components and tools that require high wear resistance and hardness.
