The difference between S235JR and S275JR steel
Products Description
The main difference between S235JR and S275JR is their yield strength. S235JR has a minimum yield strength of 235 MPa, while S275JR has a minimum yield strength of 275 MPa. This means that S275JR is stronger than S235JR and is typically used for more demanding applications, such as heavy machinery, high-rise buildings, and large structures.
In addition to their different yield strengths, S235JR and S275JR also have different tensile strengths and elongation properties. S235JR has a tensile strength of 360-510 MPa and an elongation of 26%, while S275JR has a tensile strength of 410-560 MPa and an elongation of 23%.
In terms of chemical composition, both grades of steel have similar levels of carbon, manganese, phosphorus, and sulfur. However, S275JR contains slightly more carbon and manganese than S235JR, which contributes to its higher strength.
