The core of maintaining carbon steel turned parts lies in rust prevention, cleaning, and proper storage. Daily protection can significantly extend the lifespan of parts and maintain stable performance.
Rust Prevention (Key Step) Due to its high carbon content and lack of corrosion-resistant alloying elements, carbon steel is highly susceptible to oxidation and rust in humid environments. The following measures should be taken:
Oiling Protection: After processing or before long-term storage, apply a light rust-preventive oil (such as L-AN15) evenly to the surface to form a protective film, preventing moisture and oxygen from contacting the metal surface.
Environmental Control: Store parts in a dry, well-ventilated environment, keeping the relative humidity below 50%; desiccants (such as silica gel) can be placed to absorb moisture.
Short-Term Protection: For frequently used workpieces, wipe away sweat and water stains promptly after each use and apply a thin layer of machine oil for effective rust prevention.
Inspection and Maintenance
Regular Inspection: Check monthly for rust spots, scratches, or deformation. If early rust spots are found, gently sand them with fine sandpaper and reapply oil.
Avoid Impacts: Store items separately, avoiding stacking or squeezing that could damage the surface, affecting precision and the integrity of the anti-rust layer.
Maintenance of Special Structural Components
Threaded or Grooved Parts: Clean accumulated debris from the grooves to prevent moisture buildup and localized corrosion; use compressed air to blow clean before applying oil.
Thin-Walled Sleeves: Avoid deformation under pressure; vertical hanging or storage using a dedicated bracket is recommended.
