S275N Steel: Properties, Uses, and Advantages

[ad_1] S275N steel is a normalized, weldable fine-grain structural steel, commonly used in the construction industry. It offers high yield and tensile strength, making it suitable for a range of applications. In this article, we will explore the properties, uses, and advantages of S275N steel.

プロパティ：
S275N steel belongs to the EN 10025-European Standard for structural steel, which specifies technical delivery conditions for non-alloy structural steels. It is a normalized steel with a minimum yield strength of 275 MPa. This steel grade also has good weldability and high resistance to brittle cracking.

The chemical composition of S275N steel typically includes carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), nitrogen (N), and trace amounts of alloying elements such as copper (Cu) and chromium (Cr). This composition provides the steel with excellent strength and toughness, while still maintaining good formability.

用途:
S275N steel finds its applications in a variety of structural components, where high strength is required. One of its primary uses is in the construction industry, where it is utilized in the manufacturing of buildings, bridges, and other structures. It is also commonly used in machinery, equipment, and vehicles for load-bearing purposes.

Due to its weldability and high resistance to brittle cracking, S275N steel is often used in welded structures. Its fine-grain structure ensures excellent toughness, making it suitable for applications subjected to heavy impact loads. Thus, it is frequently found in crane booms, truck frames, and supporting structures.
