If blade corrosion is your main issue, then PrimeBlade 400 is our answer, our most corrosion resistant doctor blade. The moderate carbon content, while high enough to allow for an appropriate hardening, allows for retention of chromium where it is most needed, i.e., for corrosion protection. Addition of molybdenum further enhances the anti-corrosive properties of this blade.

– Excellent corrosion resistance
