European weathering steel grades
Weathering steel is a special type of steel covering steel that is often used in outdoor construction. This type of steel is designed to withstand the elements on the exterior of a structure like wind, rain, and rust. In the European market, there are several different grades of weathering steel that have been developed for different applications.
One of the most popular grades of European weathering steel grade is S355J2W+N. This grade is used for a variety of structural applications such as bridges, buildings, fencing, and even artwork. It offers excellent corrosion resistance, especially when exposed to salt water or other harsh environments.
Another grade of weathering steel commonly used in Europe is S355J0WP. This grade is commonly used in applications where a slight degree of corrosion protection is needed. It offers good resistance to pitting, crevice corrosion, and is best used in coastal applications. This grade is often used in facades and marine structures where aesthetic appearance is important.
The S355J2WP grade is a modified version of the S355J2W+N grade. This grade offers very good total atmospheric corrosion resistance and is often used in applications where a high degree of corrosion resistance is required. This grade is often used in shipbuilding and exterior cladding applications.
The S355J2G2W grade is a low alloy form of the S355J2W+N grade. This grade offers good atmospheric corrosion resistance, yet does not have the same high level of structural properties as the S355J2W+N grade. This grade is often used in art sculptures, lighting, and other ornamental components.
The S355K2G1W grade is a modified form of the S355J2W+N grade. Like the S355J2W+N grade, it offers excellent corrosion resistance and is often used in applications where a higher degree of rust resistance is needed. This grade is best used in harsh, outdoor settings such as offshore oil rigs and chemical plants.
The S355J0W grade is a modified version of the S355J2W+N grade. It offers improved corrosion resistance over the S355J2W+N grade and is often used in structures that are exposed to salt water or other extreme environments. This grade of weathering steel is often used in bridges and facades, offering a unique and attractive appearance.
Finally, the S355K2G3 grade is a modified version of the S355J2W+N grade. This grade offers improved welding characteristics over the S355J2W+N grade, making it ideal for complex welded joints. This grade is commonly used in the offshore oil and gas industry and is great for structures exposed to extremely harsh environments.
European weathering steel grades offer a wide range of applications and performance levels. Depending on the specific application, different weathering steel grades should be considered. By understanding the differences between the grades and selecting the right grade for the application, you can ensure that your structure can withstand the elements and last for years to come.
