This work presents a new treatment for ferritic stainless steels. The Solution Heat Treatment after Plasma Nitriding (SHTPN) of AISI 409 samples resulted in a nitrogen-rich martensitic layer, thicker than 600 μm, and with 500 HV (4.90 GPa) until 200 μm. Polarization curves prove that surface hardening has not compromised corrosion resistance.
