While the difference between A36 and Q235B is as follows:Different Yield Point (A36=250MPa, Q235B=235MPa); Different Tensile Strength (A36=400-550MPa, Q235B=375-500MPa); Different element content requirements:(A36:C is equal to or less than 0.25%, Si is Q235A spiral steel pipe - Longtaidi(R) pipesQ235A toughness and ductility is good, there is a certain degree of elongation, and having a good weldability and hot workability. Q235B (GB ) - Worldwide equivalent gradesWorldwide equivalents of grade Q235B (China:GB ) ??? According EN 10250-2:2000 steel S235JRG2 also named 1.0038 ???

Q235B Included in 3 standards (China) Chemical composition C < 0.22 Si < 0.35 Mn < 1.4 P < 0.045 S < 0.045 Cr < 0.3 Ni < 0.3 Cu < 0.3 N < 0.008 As < 0.08 Fe Rest It's allowed to exceed N content up to 0.014% in finished products. On exceeding N for every 0.001% max P content reduces by 0.005%. SS400 steel plate and Q235 steel plate - Jaway Steel.SS400 is basically equivalent to Chinas 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, Ps composition less than 0.050. The yield strength of Q235 is greater than 235MPa, and the yield strength of SS400 is 245MPa.
