Coating on Hardened EN31?

We would like to coat a corrosion resistant coating on EN31 components hardened to Rc 59 to Rc63. The coating should offer corrosion resistance of about 240 Hrs. in Neutral Salt spray. Please suggest a good and economical coating. Surface finish of Ra 1.2 micron after coating or better would be preferred.

Cathodic Electro-Deposited Black paint is a good economical non embrittling coating that will suit your function.
