EN 10025 is the latest European Regulation for the introduction of the steel standard. It was first developed in 1993 and immediately replaced all existing national standards in the United Kingdom and other European countries, covering the materials and design of structural steel used in the vast majority of construction works throughout Europe.

The EN 10025 Fe690-2 is a European standard for structural steel products. It provides a minimum yield strength up to 355 N/mm² under nominal thickness up to 16 mm, with a range of product options for a specific strength category. The mechanical and chemical requirements for EN 10025 Fe690-2 must be met to ensure compliance with the standard. In addition to that, the performance requirements must be met.

The European Standard, {stnadard}, is an important specification for structural steel in the construction industry. It aims to bring unity and facilitate the free movement of goods across European nations. It provides the essential requirements for classifying, welding, cutting and producing structural steels. Additionally, its requirements ensure that all structural steel components intended for use in the construction industry are supplied in accordance with the specified standards and regulations.

EN 10025 steel is available in a broad range of grades, including S355J0, S355J2, S355K2, S355N, S355NL, S420J0, S420J2, S420K2, S460N, and S460NL. The chemical composition of each grade reflects the intended use of the product. For example, S355J0 is a structural grade steel with a specified minimum yield strength of 275 MPa and a tensile strength of 410-550 MPa. It has a low carbon content of .18% (max) along with an addition of .20-.50% manganese.

EN 10025 1.0116 steel is a structural steel with superior thermal properties, suitable for use in the construction of buildings and other structures. Its thermal conductivity, thermal diffusivity, and thermal expansion make it well-suited for a variety of applications, including power generation and heating. Additionally, EN 10025 1.0116 steel is highly resistant to corrosion and can be used in the construction of marine structures and pipelines. The thermal properties of EN 10025 1.0116 steel can be improved through alloying, coating, and heat treatment for applications in extreme environments.

EN 10025 1.0114 steel is typically weldable and heat-treatable. It usually comes in a normalized or annealed state, but it can be obtained in a quenched and tempered state. Normalizing is often done on EN 10025 1.0114 steel in order to remove any stresses that could have been introduced during hot rolling or cold forming processes, while tempering is done in order to improve tensile strength and hardness.

EN 10025 1.0553 steel is widely used in many industrial and engineering applications due to its excellent mechanical properties. Some of the benefits of using EN 10025 1.0553 steel include:
• High strength: The high strength of EN 10025 1.0553 steel makes it ideal for applications where a high load-bearing capacity is required.
• High ductility: EN 10025 1.0553 steel has good ductility and can be shaped and formed into various shapes and sizes. This makes it suitable for welded constructions.
• High corrosion resistance: EN 10025 1.0553 steel has a high corrosion resistance, making it ideal for use in corrosive environments.
• Low maintenance: EN 10025 1.0553 steel requires minimal maintenance, since it is highly durable and resistant to wear and tear.

The chemical composition of EN 10025 steel is of paramount importance for its performance characteristics. It is composed of a variety of components, including carbon, manganese, phosphorous, sulfur, silicon, chromium and molybdenum. These components are added in various amounts and create different mechanical properties, depending on the grade and classification.

The steel products must also meet certain performance requirements to be in compliance with the EN 10025 S275JR. These are usually tested by a destructive testing, such as hardness, flexural strength, and corrosion resistance. The mechanical properties are retrieved by placing a specimen under tension, while corrosion resistance is tested by both destructive and non-destructive methods.

EN 10025 S235J2G3 steel is typically weldable and heat-treatable. It usually comes in a normalized or annealed state, but it can be obtained in a quenched and tempered state. Normalizing is often done on EN 10025 S235J2G3 steel in order to remove any stresses that could have been introduced during hot rolling or cold forming processes, while tempering is done in order to improve tensile strength and hardness.
