Products Description
Q235 steel is a plain carbon structural steel which is widely used in China. Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades: Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3 (0.284 lb/in3), tensile strength is 370-500 MPa (54-73 ksi); yield strength is 235 MPa (34 ksi) for steel bar diameter or plate thickness ≤ 16mm. Since it is mild steel, the material is commonly used directly without heat treatment. Q235 material has moderate strength, in the case of higher strength requirements, Q275 or high-strength low alloy structural steel Q355 (former Q345) can be selected.
