Polarization curves show that compared with that of 304 stainless steel, the alloys exhibits lower corrosion rate in 0.5 mol H2SO4 solution, however the pitting corrosion resistance is superior to that of 304 stainless steel in 1 mol NaCl solution.
极化曲线结果表明,在0.5mol/L的H2SO4溶液中的,与304不锈钢相比,该系合金具有较低的腐蚀速率;在1mol/L的NaCl溶液中,该系合金的腐蚀速率与304不锈钢相当,但是其抗孔蚀的能力要优于304不锈钢。
