Carbon Steel Blade, Item CL-30 Doctor Blade
The CL-30 carbon steel blade features superior abrasion resistance compared to the CL-20 doctor blade and uses high quality, German ZAPP 2067 cold rolling carbon steel with overall performance that is 20% better than the base materials of the CL-20. This ensures the CL-30 blade effectively removes greater amounts of ink to ensure a clear printing result.
A heat treatment process has improved the durability and corrosion resistance of the blade, making it suitable for 250m/minute and higher printing press speeds, as well as for use in a variety of other printing presses to remove excess ink.

- The hardness levels of the CL-30 blade and CL-20 blade are the same. Blades with a high hardness reduce wear on the cylinder and anilox rollers.
- An improved microstructure gives the blade a better durability and reduces burrs in the blade edge.
- The precise polishing process prevents ink impurities from sticking to the blade surface, thus ensuring a clearer print pattern.
- Compared to CL-20, the blade is more stable in property and its service life can be up to 180000 cylinder rph for black printing.
