Product Details

Ferritic soft magnetic 430FR stainless steel round bar for solenoid valves
Free Machining Ferritic stainless steel (400 Series) 430FR is a ferritic stainless steel designed
for soft magnetic components operating in corrosive environments.
The 17.00% - 18.00% chromium makes corrosion resistance similar to 430F.
The increased silicon content in this alloy allows increased mag-netic characteristics over 430F
in the annealed condition.
430FR has exhibited superior and consistent performance due to its higher electrical resistivity.
The alloy was developed for applica-tions that require a weak coercive magnetic force
(Hc =1.88 – 3.00 Oe [150 – 240 A/m]) as needed in solenoid valves.
Our controlled processing allows magnetic properties to be typically superior to industry norms.
430FR has an increased hardness over 430F, due to the increased silicon levels, reducing the
deformation that occurs during the oscillation impacts that occur in AC and DC solenoid valves.
430FR is chemically balanced to provide superior ma-chinability and deliver heat to heat consistency
that is unsur-passed in the industry. Once an optimum machining setup has been established,
machinists can take advantage of increased machining efficiency rates (run ―lights-out‖ production).
