Products Description
1, the standard formulation party is different
A36 is the material of American standard ASME standard (equivalent to ASTM specification), SS400 is the material of Japanese standard JIS G3101(rolled steel for ordinary structure), and Q235 is the material of national standard GB/T700 standard.
2, the content of Mn element in A36 is not used because of the thickness of the plate (or the diameter of the round steel), and the content below 20mm does not contain Mn. Q235 requires the content of C, Si, Mn, S, P and other elements, but SS400 only requires S and P to be less than 0.050, and other requirements are not made. Chemical composition of the three:
①Q235 grades A, B, C, D (GB/T 700-2006)
Grade Q235A contains C 0.14-0.22% Mn 0.30-0.65% Si ≤ 0.30%S ≤ 0.050P ≤0.045
Grade Q235B contains C 0.12-0.20%Mn 0.30-0.70%Si ≤ 0.30%S ≤ 0.045p ≤0.045 (with the consent of the demander, the carbon content may not be greater than 0.22%)
Grade Q235C contains C ≤0.18% Mn 0.35-0.80% Si ≤ 0.30%S ≤ 0.040p ≤0.040
Grade Q235D contains C ≤0.17% Mn 0.35-0.80% Si ≤0.30% S ≤ 0.035p ≤0.035
②ASTM 36 contains C ≤ 0.26%P ≤ 0.04%S ≤ 0.05%Si ≤0.40%
Cu (when copper steel is specified) ≥0.20%
③SS400 contains S ≤0.050% and P ≤0.050%
