Material Notes:

Description: Ugine IMRE™ is a chromium stainless steel with improved magnetic properties used in solenoid valves. IMRE™ is at 18% chromium ferritic stainless steel with 2% Mo designed to withstand more corrosive environments than T430 stainless steel. The grade was developed for magnetic applications requiring a very low coercive magnetic field and a very high permeability. IMRE™ is chemically balanced to offer excellent magnetic properties and superior corrosion resistance with excellent machinability and delivers heat to heat consistency. Once an optimum machining setup has been established, machinists can take advantage of increased machining efficiency rates (run “lights-out” production)Application: Solenoid valves, fuel injectors, irrigation valves and electro-mechanical devices.Information provided by Schmolz + Bickenbach
