Q235 Steel - COSASTEEL

Apr 16, 2021 · Because the mechanical properties of these three grades are similar, they can be replaced within a certain range. Heat Treatment. 235 belongs to low-carbon structural steel with a carbon content of about 0.12%-0.2%, which is equivalent to ordinary 10 and 20 steel. The hardness does not change much after quenching.sp.info What is Q235 steel grade? Structural steel gradeSS400 is basically equivalent to China’s Q235 (equivalent to Q235A). However, there are differences in specific indicators, Q235 has the requirement for chemical composition of C, Si, Mn, S, P, but SS400 only asked S, P’s composition less than 0.050. The yield strength of Q235 is greater than 235MPa, and the yield strength of SS400 is 245MPa.sp.info Automotive Sheet Metal SAPH440 and Q235 Formability Experiment material used SAPH440 and Q235, their thickness are 2.0mm, their chemical composition as shown in Table 1[3]. Tab. 1 SAPH440 and Q235 chemical composition (w)% Type of material C Si Mn P S Als SAPH440 0.21 0.3 1.5 0.03 0.025 0.01 Q235 0.22 1.4 0.35 0.045 0.05 - Experiment Methodssp.info Q235 Steel Plate Equivalent Steel Standard-ASTM A36Substitution of A36, SS400 and Q235 steel plate. Although the Q235 steel grade steel plate has lower mechanical properties than A36 and SS400 material, but in actual operation process, as long as the buyers do not have special requirement, often these three kinds of materials can be substituted.
