Improved corrosion resistance for solenoids

A new alloy known as Carpenter Chrome Core® 29 Solenoid Quality stainless may be considered for use in corrosive, high purity environments such as those encountered in the semiconductor manufacturing industry and other corrosive aqueous environments. The new alloy, developed by Carpenter Technology Corp., is a soft magnetic ferritic grade that offers superior corrosion resistance while satisfying the need for a metallurgically clean material suitable for electropolishing. Chrome Core 29 Solenoid Quality stainless provides significantly better corrosion resistance than any other material in Carpenter’s family of solenoid-quality alloys. Its corrosion resistance is greater than that of Carpenter’s recently developed Chrome Core® 18-FM Solenoid Quality stainless, and approaches that of Type 316L stainless steel.
