Doctor blades made from 4037 stainless steel provide high durability and corrosion resistance, ensuring stable performance in demanding printing environments. With a hardness rating of up to 630HV, these metal doctor blades maintain edge stability over extended use, reducing the frequency of replacements. Designed for water-based and high-pH inks, they also perform well with metallic and specialty inks. The strong material composition resists chemical wear, ensuring consistent ink transfer and reliable print quality throughout long production runs.

Key Features

Higher Hardness (600-630 HV): The increased hardness provides superior wear resistance, making the blade particularly suitable for high-load and high-intensity printing environments. It maintains edge integrity over long production runs and reduces blade replacement frequency.
Higher Tensile Strength (2000 MPa): With enhanced tensile strength, the SL-48 offers greater stability and reliability under high-pressure operating conditions, ensuring consistent performance in demanding applications.
Precision Tolerances: Strict dimensional tolerances guarantee blade consistency during high-precision printing and coating processes. This ensures stable ink metering, clean doctoring performance, and uniform print quality across long runs.
