Stainless Steel Doctor Blade, Item SL-35 Doctor Blade
Made using 4028MO stainless steel, the SL-35 doctor blade offers outstanding corrosion resistance and anti-rust performance when compared to the SL-45 model, however, its abrasion resistance falls short of the SL-45 blade. Therefore, this doctor blade is suitable for occasions requiring high corrosion resistance and minimal requirements for abrasion resistance.
The SL-35 doctor blade features a delicate microstructure and dense grain distribution to ensure a slow and even wear, which prevents the ink from becoming polluted. The SL-35 doctor blade is suitable for ink with a high pH content, such as water based ink and coatings.

- A heat treatment process prevents wear and oxidation of the blade edge.
- Less granules resulting from blade wear at high speed printing reduces ink pollution levels.
- Compared to a standard doctor blade, the SL-35 is made of stainless steel for a better oxidation and corrosion resistance and a longer lifespan.
- The SL-35 stainless steel doctor blade is less expensive.
