S235JR steel is a commonly used non-alloy structural steel, classified according to European standard EN 10025-2. The following is the relevant information about S235JR steel:
1. Chemical composition: The chemical composition of S235JR steel includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). The exact ingredients depend on the manufacturing criteria and production process.
2. Characteristics: S235JR steel has good plasticity, weldability and processability. It has medium strength and good mechanical properties and is suitable for general structural applications.
3. Standard specification: S235JR steel conforms to the European standard EN 10025-2, which covers the technical delivery conditions of various non-alloy structural steels.
4. Application: S235JR steel is widely used in construction, bridges, machinery manufacturing, auto parts and pipelines and other fields. It is typically used in structures carrying light to moderate loads and is widely used in applications requiring good weldability.
5. Equivalent materials: S235JR steel also has equivalent materials in other standards, such as American standard ASTM A36, Chinese standard Q235B and Indian standard Fe360B, etc. There may be slight differences in chemical composition and mechanical properties between these materials.
Overall, S235JR steel is a common structural steel with good machinability, weldability and moderate strength, suitable for a variety of general structural applications. For specific projects or applications, please refer to relevant standards and codes for exact information and recommendations.
