Q235 ordinary carbon structural steel is also called A3 steel.
Ordinary carbon structural steel-ordinary plate is a steel material.
Q stands for the yield limit of this material. The latter 235 refers to the yield value of this material, which is about 235 MPa. With the increase of the thickness of the material, the yield value decreases. Due to the moderate carbon content, the comprehensive performance is good, and the strength, plasticity, and welding properties are well matched. It is the most widely used.
