  1. Description

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 430F, due to the increased silicon levels, reducing the deformation that occurs during the oscillation impacts that occur in AC and DC solenoid valves. Ugitech’s 430FR is chemically balanced to provide superior machinability and deliver heat to heat consistency that is unsurpassed in the industry. Once an optimum machining setup has been established, machinists can take advantage of increased machining efficiency rates (run ―lights-out‖ production).

Free Machining Ferritic stainless steel (400 Series).

  1. Applications

(1)Solenoid Valves


5.Forging (Hot Working)

Ugitech’s 430FR is very workable at elevated temperatures. The alloy is softer and more ductile than austenitic alloys and will shape with relatively little force. The high ductility of the alloy allows thin section parts to be readily obtained. Hot forging may be done by uniformly heating between 750°C/1200°C (1382°F/2192°F). No special cooling precautions are needed. Forgings may be air cooled.

The customer
We offer this product to a customer from India, who is cooperating with us for the first time.He needs an SS430FR round rod with a value of 10mm, but has not given a specific length, and he is also temporarily unable to determine the length. Our suggestion is that it could be tentatively set as 2500mm, and the client accepted our suggestion.
