Q235 ordinary carbon structural steel, also known as A3 steel. Ordinary carbon structural steel - plain plate is a type of steel material. Q represents the yield limit of this material, followed by 235, which refers to the yield value of this material, around 235MPa. And as the thickness of the material increases, its yield value will decrease. Due to its moderate carbon content, good comprehensive performance, and a good combination of strength, plasticity, and welding performance, it is the most widely used.
