The morphology of Q235 steel after burnishing on sandpaper is displayed in Fig. 4 (a). After the Q235 steel is polished, the entire surface is very smooth, and the scratches after sanding are faintly visible. Fig. 4 (b) is the SEM topography of Q235 steel soak at uninhibited solution. The entire Q235 steel interface was drastically corroded by
The micromorphologies of the corrosion products on the Q235 steel and HSCI surfaces after being immersed for the 720 h in a near-neutral pH soil solution are presented in Fig. 2, and the corresponding EDS results are shown in Table 1. The corrosion products on the Q235 steel surface have a layered structure (Fig. 2c).

Steel grades ASTM A36 and SS400 under JIS G3101 both are common used carbon structure steels,mild steels.When rolling steel plates ASTM Grade A36,As rolled or Controlled rolled is ok for thickness belows 40mm (1.5inch) normally.If above 40mm (1.5inch),customers can choose Normalized for improve steel property.Stee plates SS400 is also the same. Electrochemical Comparative Study of Q235 steel and SCP1, SCP2 and SCP3 solutions are all lower than 0.014 A/cm2, while the current density of Q235 steel in SCP4 solution reached to 0.0415 A/cm2, but still far below the criterion for active corrosion (0.1 A/cm2) . The corrosion rate of Q235 steel in each solution was slightly higher than 304 SS.
