The strength of TMT bars varies significantly with different grades. Higher-grade TMT bars, such as Fe550 and Fe600, exhibit greater yield strength compared to lower grades like Fe415 and Fe500. For instance, Fe415 typically has a yield strength of 415 MPa, while Fe600 can reach up to 600 MPa or higher. This variation in strength allows engineers to select TMT bars according to the sp... https://bit.ly/3KV51a1
