Chemical composition

Unalloyed hollow section steel for steel structure
Analyze the melting chemical composition of products with thickness ≤65mm
GRADE	COMPOSITION % MAX

Meaning of chemical composition：

Carbon (C) : Carbon is the main element that determines the strength and hardness of steel.
Silicon (Si) : Silicon is mainly used as a deoxidizer in steel, which helps to improve the strength and hardness of steel.
Manganese (Mn) : Manganese is an important element to improve the strength and hardness of steel, and also helps to eliminate the adverse effects of sulfur.
Phosphorus (P) and sulfur (S) : Phosphorus and sulfur are harmful elements in steel, which will reduce the plasticity and toughness of steel. The EN10210 standard imposes strict limits on the content of these two elements.
Nitrogen (N) : Nitrogen in steel may lead to aging phenomenon, affecting the performance of steel.

What are the environmental benefits of using EN 10210 S275J2H HOLLOW SECTION?

1. Durability and long life:

- EN 10210 S275J2H HOLLOW sections are made of non-alloyed and fine-grained steel to ensure their strength and durability. This durability means that the product can last longer and be replaced less frequently, thus reducing resource consumption and waste generation.

2. Recyclability:

- Steel is a recyclable material and the use of EN 10210 S275J2H HOLLOW SECTION helps to increase the recovery rate of materials in construction and engineering projects, reducing the need for new raw materials.

3. Surface coating:

- These hollow sections can be provided with different surface coatings to enhance durability and service life. Proper coatings can reduce corrosion and maintenance requirements, thereby reducing environmental impact.

4. Reduce material waste:

- Due to the high strength and good formability of EN 10210 S275J2H HOLLOW SECTION, it can be used to manufacture various structural components, reducing material waste and improving material utilization.

These environmental advantages make EN 10210 S275J2H HOLLOW SECTION a sustainable and environmentally friendly building material choice.
