P750 Nonmagnetic Steel

P750 Nonmagnetic Steel is a high-strength austenitic alloy designed for applications requiring stable non-magnetic performance and excellent mechanical properties. It combines corrosion resistance with superior toughness and machinability.

• Precision Measuring Instruments
  Used in micrometers, gauges, and precision tools where magnetic interference must be avoided.

• Electronic and Medical Equipment
  Ideal for MRI-compatible components, medical sensors, and electronic housings requiring non-magnetic properties.

• Molds and Tooling
  Applied in high-strength nonmagnetic mold bases and inserts to prevent distortion or attraction in magnetic fields.

• Aerospace and Defense Components
  Suitable for aircraft instruments, navigation devices, and magnetic-sensitive assemblies.

• Marine and Offshore Engineering
  Used in subsea tools, fasteners, and structures where both corrosion resistance and nonmagnetic performance are critical.

• Chemical and Petrochemical Processing
  For valves, pumps, and instrumentation exposed to corrosive environments and requiring non-magnetic stability.

Q1: What is P750 Nonmagnetic Steel?
A1: P750 is a high-strength austenitic stainless steel designed to maintain stable non-magnetic properties even after cold working. It combines excellent corrosion resistance, toughness, and machinability, making it ideal for precision and magnetic-sensitive applications.

Q2: Is P750 steel completely non-magnetic?
A2: Yes. P750 maintains a magnetic permeability of ≤1.01 µ, ensuring it remains effectively non-magnetic even under mechanical stress or after machining.

Q3: What are the main advantages of P750 compared with standard stainless steels?
A3: P750 offers higher strength, better non-magnetic stability, and improved corrosion resistance than standard grades like 304 or 316. It also performs well under both cryogenic and elevated temperatures.

Q4: What are the typical applications of P750 nonmagnetic steel?
A4: It is widely used in measuring instruments, medical and electronic equipment, mold bases, marine components, and chemical process instruments.

Q5: Can P750 be machined and welded easily?
A5: Yes. P750 can be machined and welded using conventional stainless steel techniques, but to preserve nonmagnetic properties, heat input should be controlled, and post-weld cooling should be gradual.
