Strength adaptability
S235JR: The strength grade is 235MPa, which is suitable for general building structures and bridges, etc. It can provide basic bearing capacity for buildings. In general building structures and bridges, its good bearing capacity and earthquake resistance can effectively improve the structural safety and stability of buildings.
S275JR: It is a low-alloy high-strength structural steel with moderate strength, which can meet the needs of various buildings and structural engineering, such as heavy machinery.
S355JR: The strength grade reaches 355MPa. The higher strength makes it suitable for structures with high bearing requirements, such as large bridges and high-rise buildings, which can ensure the safety and stability of the structure.
Impact toughness
The "JR" in S235JR, S275JR, and S355JR indicates that its impact toughness is below 27J, and the impact test of S355JR is carried out at room temperature. This characteristic enables the steel to maintain a certain stability when impacted, ensuring the safety of the structure.
Chemical composition advantages
S235JR: It is a low-carbon steel with a carbon content of about 0.16-0.23%. The content of impurity elements such as sulfur and phosphorus is low, not more than 0.045% and 0.045% respectively, which makes the steel have good welding performance and mechanical processing performance.
S275JR: The carbon content is about 0.21-0.27%. The content of impurity elements such as sulfur and phosphorus is slightly higher but not more than 0.040% and 0.040% respectively, making its strength and hardness relatively high, and also has good processing performance.
S355JR: It is a medium-carbon steel with a high carbon content of about 0.28-0.34%. The content of impurity elements such as sulfur and phosphorus is relatively low, not more than 0.040% and 0.040% respectively. The higher carbon content makes its strength and hardness higher and has good mechanical properties
