What is the yield strength of steel plate Q235B

The yield strength of steel plate Q235B varies depending on the thickness of the plate. Generally, for plates with a thickness of less than 16mm, the yield strength is 235MPa. For plates between 16mm and 40mm thick, the yield strength is 225MPa. And for plates with a thickness greater than 40mm, the yield strength decreases further to 215MPa.

It should be noted that the yield strength is the amount of stress required to cause permanent deformation in the steel. Beyond this point, the material will not return to its original shape when the stress is removed.

Steel plate Q235B is a type of carbon steel commonly used in construction, bridges, and other structural applications. Its mechanical properties make it suitable for a wide range of applications, including high-stress environments. However, it should be carefully selected and tested to ensure that it meets the specific requirements of the intended application.
