S275N is a European standard (EN) low alloy structural steel, they have excellent mechanical properties and corrosion resistance, and are widely used in construction, bridges, machinery, petrochemicals, marine engineering and other fields.
The composition of S275N is mainly composed of carbon (C), silicon (Si), manganese (Mn) and other elements. Among them, carbon is the backbone element of steel, which can increase the strength and hardness of steel, but also reduce the plasticity and toughness of steel. Silicon and manganese can form a solid solution with carbon, increasing the strength and hardness of steel, while maintaining the plasticity and toughness of steel. In order to increase the strength and hardness of steel, small amounts of phosphorus (P), sulfur (S) and other elements are also added.
S275N and S275NL are widely used in construction, bridges, machinery, petrochemicals, marine engineering and other fields. In these fields, S275N is mainly used to manufacture large pressure vessels, reactors, towers and other key equipment. They are widely used in these fields due to their good overall performance and cost-effectiveness, which can ensure the safety and stability of the equipment.
