Seeking Corrosion Resistant Finish Needed for 1050 Steel Laminations

Need a corrosion-resistant finish for 1050 steel laminations. Maximum dimensions of laminations are about 9.5" by 3", thicknesses range from .025" to .110" thick.

Quantities range from 0.5 million to 3 million per year.

Must resist corrosion in a de-ionized water fog for 72 hours if it is an oxide finish, and 120 hours if it is a plated finish, per ASTM D1735.

We know black oxide is an option, and want to get quotes for that finish, but we want to investigate other finishes that will help distinguish our product from those of competitors.

If the finish is such that temper colors or other stains are visible after finishing, we will need to shot blast with a #7 or #8 glass bead before finishing for a uniform color.

Black oxide is an excellent choice for your application. The corrosion resistance you are seeking will be determined by the after finish that is applied on top of the black oxide. Check the Metalguard line of RP's. We have several that will fit your requirements.
