HPM75 is a high-performance non-magnetic, pre-hardened stainless mold steel, designed for applications requiring corrosion resistance, high machinability, and excellent polishability. Its non-magnetic properties make it ideal for specific molding and precision machining applications.
Plastic Injection Molds – Ideal for molds used in humid environments or requiring non-magnetic properties.
Optical & Transparent Plastic Molds – Used in lenses, medical plastic components, and food packaging due to its excellent polishability.
High-Precision Electronic & Medical Equipment – Preferred for sensitive instruments requiring non-magnetic characteristics.
Mold Bases & Structural Components – Applied in high-end mold bases, precision mechanical parts, and corrosion-resistant components.
| Steel Grade | Hardness (HRC) | Corrosion Resistance | Machinability | Polishability | Non-Magnetic |
|---|---|---|---|---|---|
| HPM75 | 38–42 | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ✅ Yes |
| 420 SS | 48–52 | ⭐⭐⭐ | ⭐⭐ | ⭐⭐ | ❌ No |
| S136 | 50–52 | ⭐⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐⭐ | ❌ No |
| 1.2083 | 50–52 | ⭐⭐⭐⭐⭐ | ⭐ | ⭐⭐⭐ | ❌ No |
| 304 Stainless Steel | Annealed | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐ | ✅ Yes |
Compared to 1.2083 or S136, HPM75 is easier to machine and does not require heat treatment, while maintaining excellent corrosion resistance and non-magnetic properties.
🔹 Summary: Why Choose HPM75 Non-Magnetic Mold Steel?✔ Non-magnetic properties make it ideal for precision electronic & medical applications.
✔ Corrosion resistance & high polishability, suitable for optical, food-grade, and medical plastic molds.
✔ Pre-hardened (38–42 HRC), eliminating heat treatment costs and reducing production time.
✔ Good machinability & dimensional stability, ensuring high-precision manufacturing.
