Luluhawa Corten Steel
Weathering Corten steel is a corrosion-resistant structural steel designed for outdoor exposure. The name potong comes from the combination of rintangan kakisan (Cor) dan kekuatan tegangan (Ten).

Weathering Corten steel is a type of atmospheric corrosion-resistant steel widely used in architecture, infrastruktur, dan reka bentuk landskap. This steel develops a protective rust-like surface layer apabila terdedah kepada persekitaran luar. The layer slows further corrosion and protects the internal metal, giving the steel its characteristic brown appearance.
Because of its durability and distinctive surface, weathering Corten steel is commonly used in jambatan, fasad bangunan, struktur taman, and outdoor steel products.
Why It Is Called Corten Steel
The name potong comes from two key performance characteristics of the material:
| Term | Meaning | Penerangan |
|---|---|---|
| Cor | Rintangan kakisan | The steel resists atmospheric corrosion through the formation of a protective rust layer |
| Ten | Kekuatan tegangan | The steel maintains high structural strength for engineering applications |
Gabungan daripada rintangan kakisan dan kekuatan tegangan led to the name Batang korten. The material was originally developed for structural applications where steel would be exposed to weather without protective coatings.
How Weathering Corten Steel Works
When exposed to rain, oksigen, and changing temperatures, Corten steel undergoes a controlled oxidation process.
-
Initial Surface Rusting
The steel surface begins to form rust when exposed to moisture and air. -
Pembentukan Patina Pelindung
Alloying elements in the steel help create a dense oxide layer that adheres tightly to the surface. -
Stabilization of the Surface Layer
Lama kelamaan, the rust layer stabilizes and prevents further deep corrosion.
This process allows weathering steel to protect itself naturally without paint or coating.
Typical Chemical Elements in Corten Steel
Weathering steel contains specific alloying elements that help form the protective patina.
| unsur | Fungsi |
|---|---|
| Tembaga (Cu) | Promotes formation of protective rust layer |
| Chromium (Cr) | Meningkatkan ketahanan kakisan |
| nikel (Dalam) | Meningkatkan ketahanan cuaca |
| silikon (Dan) | Meningkatkan rintangan pengoksidaan |
| Fosforus (P) | Helps stabilize the rust layer |
These elements allow the steel to develop a stable corrosion-resistant surface dalam persekitaran luar.
Common Applications of Weathering Corten Steel
