Yes, your Corten steel product will continue to rust, but only up to a certain point. Corten steel, also known as weathering steel, develops a skyddande rostskikt that stabilizes over time. This layer shields the underlying metal from further corrosion, slowing down the rusting process significantly.
Key Points About Corten Steel Rusting:
- Initial Rusting: When exposed to moisture and air, Corten steel starts forming a rust layer. This process typically takes 6 months to 3 years, depending on environmental conditions.
- Protective Patina: Over time, the rust layer thickens and becomes stable, reducing further corrosion. Unlike regular steel, Corten doesn’t rust through but instead forms a durable, self-healing surface.
- Environmental Factors: If your Corten steel product is in a humid, coastal, or constantly wet environment, the patina may take longer to form, and the rusting process may continue beyond the usual stabilization period.
- Maintenance Considerations: To control the rusting process, you can:
- Allow natural weathering to occur in a well-ventilated area.
- Use a rust accelerator to speed up patina formation.
- Apply a sealer to maintain the current rusted appearance and prevent further oxidation.
