    • Q235 SteelFeatures and ApplicationsData Sheet and SpecificationQ235 Steel EquivalentQ235 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). Since its mild steel, it is used directly without heat treatment.What is Q235 steel grade? Structural steel gradeSS400 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.
