Non-magnetic Round Steel bar 7Mn15Cr2Al3V2WMo HPM75

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.

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.

✔ 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.
