Carpenter Chrome Core 18-FM solenoid quality stainless was developed with optimal corrosion resistance in mind. The result was an alloy with superior corosion resistance over type 430FR solenoid quality but with similar magnetic properties. This datasheet provides information on composition and physical properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-720. Producer or source: Carpenter.
