AISI 430F EN 1.4104 DIN X14CrMoS17 Stainless Steel Round Bars
Material 430F is used where a high level of magnetic permeability
is required.
This derives from its fully ferritic structure.
Its high level of machinability allows volume throughput of
components.
430F stainless grade combines the following characteristics:
- Fair pitting and crevice corrosion resistance
- “Soft” magnetic properties. Low coercivity giving reversibly
magnetic properties in electromagnetic devices
- High magnetic permeability
- Excellent machinability
430F is the most common stainless steel grade used for
electromagnetic devices.
Although its magnetic properties are not as good as the
iron-silicon alloys, where corrosion resistance is required,
it provides an excellent combination of properties.
The processing of the grade is also important to ensure the optimum
microstructure.
The test certificate includes details of the magnetic properties
where applicable.
Applications which illustrate these features include:
Magnetic cores, solenoid valves, relays, fuel injection systems,
anti-lock braking systems, electromagnetic pumps.

Free-Machining Stainless Steel Bars
AISI 430F stainless steel round bars, drawn wire
We also produce 430FR Stainless Solenoid Quality
Type 430FR stainless has been used for solenoid valve magnetic core
components which must combat corrosion
from atmosphere, fresh water, and corrosive environments.
This grade has a higher electrical resistivity than 430F Solenoid
Quality, which reduces eddy current losses of the material.
