Product Overview
HPM75 is a specialized non-magnetic mold steel designed for industries where even slight magnetic interference can lead to machining errors, unstable tolerance, or inconsistent product quality.
It is widely used in precision molds, connectors, and electronic components, where stability is more important than just hardness.
Core Advantages
Eliminates Magnetic Interference
Prevents positioning deviation during CNC machining and EDM processing.Improves Machining Accuracy
Helps maintain tighter tolerances in high-precision components.Stable Structure, Less Deformation
Reduces dimensional variation during long production cycles.Balanced Hardness & Toughness
Not easy to deform, not easy to crack — stable in real production.Better Consistency in Mass Production
Especially suitable for high-volume precision parts.Supports Surface Hardening (Nitriding)
Improves wear resistance without affecting core stability.
Typical Problems It Solves
Parts dimension inconsistent after machining
EDM accuracy affected by magnetic materials
Mold alignment deviation during processing
High scrap rate in precision components
Tooling instability in connector molds
Applications
Precision connector molds
Electronic component molds
Semiconductor tooling
Medical precision molds
Non-magnetic fixtures
Supply Condition
Pre-hardened: HRC 28–32
Aging treated: up to HRC 40–45
Why HPM75?
Because in precision manufacturing, magnetism is often the hidden reason behind accuracy problems.
HPM75 is not just a steel — it’s a solution for stable machining and consistent quality.
