Product Introduction

Q235 is ordinary carbon structural steel. The "Q" represents the material's yield point, and the "235" refers to its yield value, which is approximately 235 MPa. This value varies with the material's specifications. Due to its moderate carbon content, it offers excellent overall performance, with a well-balanced combination of strength, ductility, and weldability, making it extremely versatile.

Among steels, this is the most common material, belonging to the general steel category. Previously known as A3 steel, it is used for various mold handles and other minor mold parts.
