Q235 Steel Q235A Q235B Q235C Q235D Equivalent, Q235 Steel (Q235A Q235B Q235C Q235D) 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, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm).
various types of structural steelwork, chemical composition and mechanical properties have been examined systematically in classifying where equivalence lies. This Professional Guide presents a comprehensive view on the equivalence of steel materials which is The difference between GB/T 700 Q235A steel plates and Both Q235A steel plates and Q235B steel plates belong to carbon steel or mild steel. According to standard GB/T 700,the distinction of Q235A steel and Q235B material mainly lies in carbon content. The carbon content of Q235A steel plates is 0.14-0.22.GB712 AH36,GB/T Grade AH36 STEEL PLATE__Steel SupplierGB 712 AH36 high Strength Chemical Composition in Tempering and Quenching. Grade.
