Essential detailsP530 non-magnetic steel undergoes a gas soft oxidation treatment to enhance surface hardness, boosting wear resistance and extending the lifespan of components. This steel is ideal for producing non-magnetic molds, bearings, and other structural parts that must remain unaffected by magnetic fields. Additionally, its high-temperature strength and hardness make it suitable for manufacturing hot work molds operating at temperatures up to 700°C–800°C.
Typical Applications:
- Aerospace
- Medical equipment
- Precision instruments
