430FR Stainless Steel






Stainless steel alloy 430FR is a free-machining solenoid quality alloy, ideal for parts that require corrosion resistance and high electrical resistivity. It has excellent corrosion resistance in fresh water, gaseous, moderately acidic, and low chlorine environments. 430FR’s high silicon levels give it increased hardness, decreased deformation from impact, and increased magnetic characteristics.
