Material Advantages of 17-4PH and the Added Benefits of MIM (Metal Injection Molding) Technology
Manufactured using Metal Injection Molding (MIM) technology Material: 17-4PH (SUS630) precipitation-hardened stainless steel Single-step molding Tensile Strength: ≥1100 MPa Yield Strength: ≥1000 MPa Hardness: HRC 38–45 (after heat treatment) Density: ≥7.70 g/cm³ High Strength and Corrosion Resistance 17-4PH offers an excellent balance of mechanical strength and corrosion resistance. After heat treatment, it achieves high tensile strength and medium to high hardness, making it ideal for automotive metal components exposed to high loads, strong vibrations, and harsh environments such as humidity and salt spray. Dimensional Stability – Suitable for Precision Structures Minimal distortion after heat treatment and low thermal expansion make it ideal for high-precision mating parts MIM enables the formation of complex geometries in a single step, reducing secondary machining and improving consistency Surface treatments such as passivation, polishing, and electropolishing enhance corrosion resistance and aesthetic quality Typical Applications Widely used in high-strength and high-precision automotive metal components, including: Car door lock cores Tailgate hinge parts Brackets for electronic parking systems Internal connectors in transmission systems Wiper drive gears Metal mounting structures for charging ports
