automotive industry used steel S355MC, Q195 and Q235 belong to carbon structural steel, which are mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Of course, there are many differences between Q195 steel and Q235 steel. 1. Different components. The chemical composition of Q195 steel: C ≤ 0.12, Si ≤ 0.30, Mn ≤ 0.50, P ≤ 0.035, S ≤ 0.040. The chemical composition of Q235 steel: C ≤ 0.22, Si ≤ 0.35, Mn ≤ 1.40, P ≤ 0.045, S ≤ 0.050. 2. The prices of automotive industry used steel S355MC, Q235 steel is higher than that of Q195 steel. 3. The mechanical properties of Q195 and Q235 steel are different. The tensile strength of Q195 steel is ≥390 MPa, yield strength is ≥195 MPa, and the elongation is ≥ 30%. The tensile strength of Q235 steel is 490 MPa, yield strength is ≥235 MPa, and the elongation is 23%.
