Describe Ugitech’s 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 magnetic 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 applications 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 4...
