1. Why Traditional Rust Prevention Is Unnecessary
2. Critical Post-Cutting Care Measures
Deburr and Smooth Cut Edges
Use a grinder or sandpaper to remove sharp burrs, micro-cracks, and heat-affected zone (HAZ) residues from the cut surface. These defects can trap moisture and cause localized pitting corrosion before the patina fully matures.Repair Damaged Patina (If Applicable)
If the original patina on the plate surface is scratched during cutting, apply a weathering steel rust accelerator to the damaged area. This triggers rapid, uniform oxidation, ensuring the repaired area matches the surrounding patina and avoids color mismatches.Avoid Contact with Dissimilar Metals
Do not stack or fasten cut S355J2W plates with carbon steel, aluminum, or galvanized steel without insulating gaskets (e.g., rubber, plastic). Direct contact can cause galvanic corrosion, especially in humid environments.Ensure Good Airflow and Drainage
Store or install the cut plates in well-ventilated areas with no stagnant water accumulation. Enclosed or waterlogged spaces will prevent the patina from forming properly, leading to uneven rusting.
