Free machining ferritic stainless steel with a better corrosion resistance for solenoids
Material number:
Standard UNS:
RoHS 2 – 2011/65/EU:
Machinability:
This steel grade exhibits very good machinability.
Hardening capability:
The Chrome Core 18-FM steel cannot be thermally hardened.
Forming:
The Chrome Core 18-FM steel exhibits a strong grain growth at the forging / forming temperature. Avoid holding time before forging.

Uses:
This Chrome Core® 18-FM steel is supplied in the soft magnetic annealed condition, ready for machining. The machined core parts can usually be use directly in the as machined condition, provided they have not been polluted or contaminated with free Fe-ions during machining or handling.
The Chrome Core® 18-FM steel is a free machining ferritic stainless steel produced by CarTech®. It features a high S-addition to improve its machinability and has a high Cr-content allowing its use in still more aggressive mediums. In addition its microstructure is stabilized with an Nb addition to improving both its corrosion resistance as well as its machinability. This steel has a high resistivity reducing the eddy current losses due to AC excitation.
