What is Corten Steel?
Cortenstahl, also known as wetterfester Stahl, is a special alloy steel highly favored in architectural and structural design. It develops a distinctive rust-like patina, adding a modern industrial aesthetic to garden landscapes, outdoor projects, and architectural facades.
One of the key advantages of Corten steel panels is their exceptional resistance to corrosion and weather-related damage. Over time, the surface naturally forms a protective oxidation layer, which prevents further rusting and enhances its durability. This evolving patina makes Corten steel both visually striking and low maintenance.
With its high strength and long lifespan, Cortenstahl is widely used for building facades, fencing, garden planters, sculptures, and other outdoor applications. Its low maintenance requirements make it a top choice for designers, offering both practicality and aesthetic appeal in modern landscaping and architecture.
Grades and Classification of Corten Steel
Corten steel, or wetterfester Stahl, is classified into different grades based on international standards, chemical composition, mechanical properties, and application scenarios. Various countries and regions have established their own specifications, ensuring that while all these materials fall under the category of wetterfester Stahl, their composition, strength, and intended use may vary.
Below is an overview of the classification criteria and key industry standards for Corten steel grades:
1. Classification of Corten Steel by Standards
Different standard organizations have established their own weathering steel specifications, including ASTM (USA), EN (Europe), JIS (Japan), and IRSM (India). While all these steels fall under the weathering steel category, their composition, strength, and applications vary based on regional requirements.
1. ASTM Standards (USA)
ASTM A588 – Commonly used in bridges and building structures, offering high strength and excellent weather resistance.
ASTM A242 – Primarily used in architectural and structural engineering, with slightly lower strength than A588 but comparable corrosion resistance.
2. EN Standards (Europe)
EN 10025-5 S355J2W+N – Features good weldability and is suitable for structural engineering applications.
EN 10025-5 S355J0WP – Designed for atmospheric corrosion resistance, widely used in building and bridge structures.
3. JIS Standards (Japan)
- JIS G3125 SPA-H – A high-strength weathering steel in Japanese standards, extensively used in railway vehicles, bridges, and shipping containers.
4. IRSM Standards (India)
IRSM 41 / 97 – A weathering steel grade specifically developed for Indian Railways, used in railway bridges and infrastructure.
These standards ensure that Cortenstahl meets the demands of various industries, from construction and transportation to infrastructure and architectural design.
2. Classification of Corten Steel by Chemical Composition
One of the defining characteristics of Cortenstahl is the addition of alloying elements such as copper (Cu), chromium (Cr), and nickel (Ni). These elements contribute to the formation of a protective rust layer, enhancing its corrosion resistance. Different grades of Corten steel vary in the concentration of these elements, leading to differences in performance and application.
Corten A vs. Corten B
- Corten A – Contains a higher phosphorus (P) content, which enhances atmospheric corrosion resistance. It is designed for thinner sheets (2.5mm-12mm) and is commonly used in architectural facades and decorative applications.

Corten B | 2-13 | 6-40 | 345 | 485 | 19 |
ASTM A588 vs. ASTM A242
- ASTM A588 – Lower carbon content, offering better weldability and higher mechanical strength, making it suitable for load-bearing structures.
- ASTM A242 – Slightly better weather resistance, commonly used in architectural decorations, railings, and non-load-bearing structures.
3. Classification of Corten Steel by Mechanical Properties (Strength and Yield Strength)
Die tensile strength und yield strength of Corten steel are key factors for its classification. Below is a table showing the yield strength und tensile strength for various grades of wetterfester Stahl:
| Steel Type | Yield Strength (MPa) | Tensile Strength (MPa) |
|---|---|---|
| Corten A | 345 | 485 |
| Corten B | 345 | 485 – 630 |
| ASTM A588 | 345 – 485 | 485 – 620 |
| ASTM A242 | 345 | 480 – 630 |
| EN 10025-5 S355J2W+N | 355 | 510 – 680 |
| EN 10025-5 S355J0WP | 355 | 510 – 680 |
| JIS G3125 SPA-H | 355 | 490 – 630 |
| IRSM 41 / 97 | 340 | 480 – 610 |
These mechanical properties help to determine the structural suitability und performance of each grade of Cortenstahl based on the intended application.
4. Classification of Corten Steel by Application Scenarios
Different grades of Cortenstahl are suited for specific applications based on their mechanical properties und corrosion resistance. Here is a breakdown of their typical uses:
