Q235
Q235 ordinary carbon structural steel is also known as A3 steel.
Ordinary carbon structural steel - general plate is a kind of steel material.
Q represents the yield limit of this material, and the yield value of this material is 235, which is about 235MPa.With the increase of the material thickness, the yield value will be reduced. Due to the moderate carbon content, the comprehensive performance is better, the strength, plasticity and welding properties are better matched, the most widely used.
Chemical composition of Q235
